B Correct answer
Explanation

DDT is an insecticide (“insect” + “cidal” – killing). It is used to kill a variety of insects and pests, particularly mosquitoes. It should be noted here that though DDT is useful but at the same time, it is a pollutant and hence, its use must be limited. Apart from DDT, all other options given here are vaccines and hence, they cannot be used to kill mosquitoes because their function is to give immunity inside our body. BCG is a vaccine against TB; ATS is Anti Tetanus Serum and DPT is a triple vaccine against diphtheria, pertusis and typhoid.
