How many cities are covered under the National Clean Air Programme?

The correct answer is the International Day of Clean Air for Blue Skies, on which the ministry held Swachh Vayu Diwas and gave away the fifth round of Swachh Vayu Sarvekshan awards. Option A names World Environment Day, the best known environmental observance and therefore the most tempting wrong answer, but it falls in June and is not tied to this event. Option B names World Ozone Day, which marks the Montreal Protocol and concerns ozone depleting substances rather than ambient air quality. Option D names World Meteorological Day, which belongs to the weather and climate services community. The link to remember is simple: clean air day, clean air survey, clean air programme. The chief guest at this edition was Justice Prakash Shrivastava, Chairperson of the National Green Tribunal, who called clean air a fundamental need rather than a luxury.

The correct answer is 14. The ministry set out the record on PM10 for the year 2025-26 against the base of the financial year 2017-18 in four steps, and every one of those steps appears among the options here, which is what makes the question worth practising. Option D gives 108, the number of cities that showed any improvement in PM10 levels. Option C gives 72, the cities where the fall in PM10 concentration crossed 20 per cent. Option B gives 26, the cities where the fall crossed 40 per cent. Only 14 cities actually met the National Ambient Air Quality Standards, which is the strictest of the four tests, and that is the answer. Learn the chain in descending order, 108 then 72 then 26 then 14, because the harder the test the smaller the count.

The correct answer is the PRANA portal. The Secretary of the ministry explained that the National Clean Air Programme gives every city a framework within which it works out its own strategy for clean air, while this portal follows the various parameters of air quality management for the cities under the programme. Option A names a portal associated with air quality information for the public, option C names the environmental clearance platform of the ministry, and option D names a scheme in the sanitation sector; none of these is what the release credits with the tracking work. Remember the trio together for revision: the programme is NCAP, the survey that ranks the cities is the Swachh Vayu Sarvekshan, now in its fifth round, and the portal that keeps the score through the year is PRANA.

The correct answer is 248. The announcement was made at the World Ozone Day function in Mumbai, where 12 refrigeration and air-conditioning manufacturers agreed to adopt that many Industrial Training Institutes. The arrangement rests on a four-party memorandum of agreement signed by the manufacturers, the Ozone Cell, the Regional Directorate of the Directorate General of Training and the State Directorate. Its purpose is to strengthen the training infrastructure for the next generation of technicians and to align classroom learning with prevailing industry standards. Options A, B and D are close-sounding figures designed to test whether the exact number has been memorised. The wider context is that safe handling of refrigerants by certified technicians is central to India's obligations under the Montreal Protocol and to the phase-out of ozone-depleting substances.

The correct answer is the Net Zero Portal and the NAPCC Dashboard. Union Minister of State Kirti Vardhan Singh launched both in Mumbai on the occasion of World Ozone Day. The Net Zero Portal is a centralised platform on which Indian entities across sectors can voluntarily register and disclose their net zero commitments, report greenhouse gas emissions and set out pathways covering clean energy, energy efficiency and carbon removals. The NAPCC Dashboard offers a consolidated digital view of implementation across the national missions under the National Action Plan on Climate Change. Options B, C and D name platforms that do not correspond to this launch. Mission LiFE was indeed mentioned in the minister's address as a framework for everyday environmental action, but no dashboard by that name was launched here, which is what makes option C a careful trap.
