The coastal clean-up under 'Swachh Sagar Surakshit Sagar' 5.0 covered how many locations?

The correct answer is Department of Science & Technology. 'Vigyan Ki Baat' is a monthly lecture series launched by DST to showcase the work of India's autonomous scientific institutions and take their achievements to a wider audience. Its first edition, held on 29 August 2026, drew more than 7,500 people from academia, research and industry, and the second edition, on 26 September 2026, will feature the Director of the S.N. Bose National Centre for Basic Sciences.

The other options were all part of the same review meeting, which is why they confuse. The Department of Biotechnology and the Ministry of Earth Sciences take part in the joint digital outreach effort, and CSIR is preparing for CSIR@85. The proposed Digital Library of Scientific Achievements is being built with CSIR-NIScPR as the nodal institution, not DST.

The correct answer is 15 lakh. During Swachh Sagar Surakshit Sagar 5.0, held from 12 to 19 September 2026, 15 lakh people took the Ocean Conservation Pledge, a commitment to keep the sea and the coast free of litter. Dr Jitendra Singh highlighted this figure while reviewing the campaign and asked that the momentum of public participation be sustained.

The other options are distractors. The pledge figure is the one most likely to be asked because it appears in the headline of the government release, alongside the 231 clean-up locations in 13 States/UTs. Ocean litter is dominated by plastic, which breaks down into microplastics and enters the marine food chain, and campaigns like this aim to change behaviour on land, where most of that waste starts, as well as to clean the beaches themselves.

The correct answer is Harit Nyayam. At the valedictory session in New Delhi on 20 September 2026, Union Minister Manohar Lal released the NGT's souvenir titled Harit Nyayam and presented its first copy to the President of India. The document chronicles the establishment, growth and achievements of the tribunal and reflects the ideas discussed at the two-day conference.

Prakriti Vandan, Harit Bharat and Paryavaran Nyay sound similar, and that is why they are here, but none of them is the title of this souvenir, so options B, C and D are wrong. Names of publications released at official events are a favourite one-liner, so remember who released it (Manohar Lal), who received the first copy (the President) and which body it belongs to (the National Green Tribunal).

The correct answer is 55 per cent. Speaking at the valedictory session of the National Green Tribunal's conference, Manohar Lal, Union Minister for Housing and Urban Affairs and Power, said non-fossil sources account for nearly 55 per cent of India's installed generation capacity. He presented this as part of India's effort to balance rapid development with environmental sustainability.

Option B, 50 per cent, is the trap. That figure is the non-fossil capacity target, which the minister said India achieved five years ahead of schedule; it is not the current share. Options A and D, 40 and 65 per cent, are not mentioned in the release. Keep the two numbers distinct in your notes: the target was 50 per cent and was met early, while the present share is nearly 55 per cent.

The correct answer is Justice Prakash Shrivastava. The release identifies him as the Chairperson of the NGT. In his valedictory address he said the two days of discussion had shown the need to move beyond identifying environmental problems to building laws, institutions and partnerships able to respond to them, and that climate action must be inclusive and equitable.

The other three all spoke at the same session but hold different offices. Justice B.V. Nagarathna is a Judge of the Supreme Court of India. Tushar Mehta is the Solicitor General of India. Manohar Lal is the Union Minister for Housing and Urban Affairs and Power, who released the souvenir Harit Nyayam. That rules out options B, C and D. When several dignitaries appear in one release, examiners often swap their designations, so match each name to its post.
