Correct answer: C. Detailed study of the Sun’s coronal mass ejections from a new Lagrange point
Notes: The ‘Aditya-L2’ mission, a follow-up to the highly successful Aditya-L1, has successfully deployed its advanced suite of instruments to the Sun-Earth L2 Lagrange point. This mission is designed for an in-depth, continuous observation of the Sun’s outer atmosphere, focusing specifically on solar flares, coronal mass ejections (CMEs), and space weather phenomena. Its strategic positioning at L2 provides an uninterrupted view of the Sun, enabling scientists to gather crucial data for predicting solar storms and understanding their impact on Earth’s communication systems and power grids, marking a significant leap in India’s heliophysics research capabilities and global contributions to space weather forecasting. This further solidifies ISRO’s position in advanced space science.

Correct answer: C. The ‘Renewables Acceleration Pact’ (RAP-2025)
Notes: The ‘Renewables Acceleration Pact’ (RAP-2025) represents a landmark agreement forged during the recent G20 Summit, which saw widespread ratification aimed at significantly boosting global renewable energy capacity. This pact outlines ambitious targets for tripling global renewable energy generation by 2030 and streamlines international financial mechanisms to support developing nations in their green energy transitions. It also includes provisions for technology transfer and capacity building, ensuring a more equitable shift away from fossil fuels. The RAP-2025 is seen as a critical step in achieving the Paris Agreement goals and addressing climate change more effectively, demonstrating a renewed commitment from major economies towards a sustainable energy future and fostering international collaboration on climate action.

Correct answer: C. Testing offline transaction capabilities and smart contract functionalities for retail users
Notes: The Reserve Bank of India (RBI) has unveiled an ambitious next phase for its Digital Rupee (e₹) pilot, primarily focusing on enhancing retail user experience and utility. This expansion specifically targets testing offline transaction capabilities, allowing users to make payments even without internet connectivity, which is crucial for financial inclusion in remote areas. Furthermore, the phase will explore smart contract functionalities, enabling automated and secure transactions for various use cases like rental agreements, insurance claims, and supply chain financing. This strategic move aims to solidify e₹’s position as a robust, resilient, and versatile digital currency, complementing physical cash and traditional digital payment methods, and pushing India towards a truly cashless economy.

Correct answer: A. Japan
Notes: India and Japan have recently solidified their strategic partnership by announcing the formation of a joint cyber defence command, specifically designed to protect critical national infrastructure. This initiative comes amidst growing global concerns over state-sponsored cyberattacks and aims to foster greater interoperability and intelligence sharing between the two nations’ cyber security agencies. The command will focus on developing joint response protocols, conducting simulated attack drills, and sharing expertise on emerging cyber threats, including those targeting energy grids, financial systems, and communication networks. This collaboration underscores a mutual commitment to enhancing regional stability and resilience against digital warfare, reinforcing the broader Indo-Pacific security architecture and highlighting the deepening trust and cooperation between India and Japan in crucial strategic domains.

Correct answer: B. Dengue
Notes: Researchers from leading institutes in India and Brazil have jointly announced a significant breakthrough in the development of a highly effective vaccine against Dengue fever. Following successful Phase III clinical trials conducted across endemic regions, the vaccine has demonstrated remarkable efficacy against all four serotypes of the Dengue virus, providing sustained protection. This collaborative effort leveraged advanced viral vector technology and extensive epidemiological data from both countries, where Dengue poses a severe public health challenge. The new vaccine is anticipated to be a game-changer in combating the widespread tropical disease, significantly reducing hospitalization rates and mortality. Regulatory approvals are now expedited, promising global availability in the near future and offering hope to millions vulnerable to this debilitating illness.
