Match List I (Source or Process) with List II (Air Pollutant) and choose the correct answer.
List I
i.Transport sector
ii.Refrigeration and air conditioning
iii.Landfills
iv.Incineration of medical waste
List II

d.HFCs
Ai-c, ii-b, iii-d, iv-a
Bi-b, ii-d, iii-a, iv-c ✓ Correct
Ci-b, ii-d, iii-c, iv-a
Di-c, ii-d, iii-a, iv-b
Correct answer: (B) i-b, ii-d, iii-a, iv-c
Explanation
The transport sector emits volatile organic carbons, refrigeration and air conditioning release HFCs, landfills give off methane, and medical waste incineration produces dioxins.
The transport sector pairs with volatile organic carbons from vehicle fuels and exhaust.
Refrigeration and air conditioning pair with HFCs used as cooling refrigerants.
Landfills pair with methane released as buried organic waste decomposes without oxygen.
Incineration of medical waste pairs with dioxins formed when chlorinated materials burn.
HFCs and methane are potent greenhouse gases, while dioxins are highly toxic persistent pollutants.
