    A)  DDT          

    B)  Eldrin

    C)  Aldrin         

    D)  Toxaphene

    Correct Answer: A

    Solution :

    DDT is an organochlorine. Now-a-days DDT is banned because it has an affinity for fatty tissues of animals which lead to biomagnification. Besides, with the repeated use of such pesticides a kind of accelerated evolution occurs to produce a resistant population of pests. Aldrin, endosulfan, eldrin are lipophilic in nature.
