What monthly average Air Quality Index did Delhi record for September 2026, described as its lowest September figure in five years?
- A.92
- B.102
- C.112
- D.122
Correct answer
Explanation
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.
