{'greenhouse effect': [3, 0, 0, 1], 'carbon dioxide': [2, 0, 5, 6], 'air pollutant': [0, 0, 0, 1], 'chlorofluorocarbon': [1, 0, 0, 6], 'sulphur dioxide': [0, 0, 0, 1], 'ozone': [3, 0, 3, 5], 'acid rain': [1, 0, 2, 3], 'contribution': [0, 1, 4, 6], 'effect': [4, 0, 2, 7]}

The question asks us to match List I (Air Pollutant) with List II (Effect) and select the correct answer using the given code. Let`s examine each option:

Option 1: Matches A with 4, B with 3, and C with 2. This means Chlorofluorocarbon is matched with topmost contribution to the greenhouse effect, Sulphur dioxide with harmful for human nervous system, and Lead compound with depletion in ozone layer in the atmosphere. However, this option does not match D with 1 (acid rain). Therefore, this option is incorrect.

Option 2: Matches A with 4, B with 1, C with 3, and D with 2. This means Chlorofluorocarbon is matched with depletion in ozone layer, Sulphur dioxide with acid rain, Lead compound with harmful for human nervous system, and Carbon dioxide with topmost contribution to the greenhouse effect. This option matches all the pollutants with their effects, so it is a possible correct answer.

Option 3: Matches A with 2, B with 1, C with 3, and D with 4. This means Chlorofluorocarbon is matched with the harmful for human nervous system, Sulph
