The minister recalled Mahatma Gandhi's stay in Champaran, where his sanitation work grew into a mass movement, in which year?

The correct answer is Arjun Ram Meghwal. He is the Union Minister of State with Independent Charge for Law and Justice, and in that capacity he led the tree plantation drive on the campus of the India International Arbitration Centre at Vasant Kunj in New Delhi. Option B, Rajiv Mani, is the Secretary of the Legislative Department and of the Department of Legal Affairs and serves as Chairperson of the arbitration centre, so he is a senior official rather than the minister. Option C, Navin Kumar Singh, is the Chief Executive Officer of the centre and thanked the dignitaries at the close of the programme. Option D names someone who did not figure in this event at all. Addressing the gathering, the minister said cleanliness cannot stop at streets and public spaces and must begin with a clean mind, pure thought and a sense of duty towards society.

The correct answer is Ek Ped Maa Ke Naam. The Department of Legal Affairs of the Ministry of Law and Justice organised the drive under that theme on the eve of Gandhi Jayanti, and it formed part of Special Campaign 6 as well as Swachhata Hi Seva 2026. Options A, C and D are plausible-sounding names for plantation or greening drives, but none of them is the theme named for this event. The minister, the law secretary who chairs the centre, and senior officers of the department and the centre planted saplings on the campus together. The programme ended with a pledge to carry on cleanliness work and to promote a greener and more sustainable environment, and the centre's leadership tied that pledge to the wider aims of the Swachh Bharat Mission.

The correct answer is the Commission for Air Quality Management, usually written as CAQM, which the ministry named as the body coordinating work with the agencies concerned. Option A, the Central Pollution Control Board, sets and enforces pollution standards across the country and runs the monitoring network, but it is not the coordinating commission for the capital region named here. Option C, the National Green Tribunal, is an adjudicating body that hears environmental cases and does not run pollution control programmes. Option D, the Indian Meteorological Department, forecasts weather and supplies the wind and temperature data that air quality forecasts rest on, which makes it a plausible distractor, but it is a weather agency rather than a pollution authority. Along with the numbers, examiners like to ask which body owns the air quality mandate for the capital region, and the answer is CAQM.

The correct answer is 102. The Environment Ministry placed the September average for Delhi at 102, and set it against 105 in 2025, 105 in 2024, 108 in 2023 and 104 in 2022, which makes it the lowest September reading across those five years. Option A, 92, is wrong because the index did not fall that far; it would have put Delhi in a better band than the moderate one the reading actually sits in. Option C, 112, and option D, 122, are both higher than any of the five September averages named, so neither can be the lowest of the run. Candidates should note that a lowest-in-five-years claim always needs the comparison set, and here the whole set is worth carrying: 102 for the current year against 105, 105, 108 and 104 for the four years before it.

The correct answer is 194 days. A daily average below 200 falls in the moderate category, and the nine months of the current year gave 194 such days, the most in the five-year comparison. Option A, 146 days, is the figure for 2022, the weakest year of the set, and is a classic trap because it belongs to the same table. Option B, 187 days, is the figure for 2025, the year immediately before, and is the nearest wrong answer a candidate can pick by confusing the two most recent years; 2024 gave 188 days and 2023 gave 193 days. Option D, 214 days, does not appear in the comparison at all. Read together with the fall in bad-air days from 127 in 2022 to 79 this year, the direction of the trend is what the release is claiming, and the figure asked for is 194.
