Assertion (A) BHC is also called gammexane or 666. Reason (R) BHC is prepared by the reaction of benzene with Cl2 in the presence of light. A. Both A and R are true and R is the correct explanation of A B. Both A and R are true, but R is not the correct explanation of A C. A is true, but R is false D. A is false, but R is true

The correct answer is: Both A and R are true, but R is not the correct explanation of A.

BHC is also called gammexane or 666. It is a chlorinated hydrocarbon insecticide that is effective against a wide range of insects. It is prepared by the reaction of benzene with chlorine in the presence of light. However, the reaction of benzene with chlorine in the presence of light does not always produce BHC. Other chlorinated hydrocarbons, such as hexachlorobenzene, can also be produced. Therefore, R is not the correct explanation of A.

A. Both A and R are true and R is the correct explanation of A.

This option is incorrect because R is not the correct explanation of A.

B. Both A and R are true, but R is not the correct explanation of A.

This option is correct because A is true and R is true, but R is not the correct explanation of A.

C. A is true, but R is false.

This option is incorrect because R is true.

D. A is false, but R is true.

This option is incorrect because A is true.
