Step-by-step solution

DDT stands for Dichlorodiphenyltrichloroethane. Its IUPAC name is 1,1,1 -trichloro- 2,2 -bis( 4 -chlorophenyl)ethane. It is prepared by heating chlorobenzene with chloral (trichloroacetaldehyde) in the presence of concentrated H ₂ SO ₄ . The structure consists of an ethane chain where carbon- 1 is attached to three chlorine atoms (trichloro), and carbon- 2 is attached to two p -chlorophenyl groups and one hydrogen atom. This matches the structure given in the first option. Answer:
