Hint: In this question it is said that when chloral is reacted with chlorobenzene which compound is going to be formed which is an important insecticide. As there are many options are given in which we have to choose the correct compound which is form by the mixture of Chloral and chlorobenzene.



Formula Used:

Complete step-by-step answer:Firstly, we get some data about our reactants,
Chloral which is also said as by the name of Trichloro acetaldehyde is a organic compound whose chemical formula is $C{l_3}CCHO$ .
Chlorobenzene is a very reactive and flammable liquid and it is also a colourless compound. Its chemical formula is ${C_6}{H_5}Cl$ .
We know that when chloral is reacted with chlorobenzene as in the presence of sulfuric acid it always forms DDT (Di chloro Di Phenyl Tri Chloro Ethane) which is also a very important insecticide which is used in agricultural process.
Therefore, as from the above data the correct answer is DDT (Di chloro Di Phenyl Tri Chloro Ethane).
Hence, the correct option is (C).



Option ‘ ’ is correct
