Statement -1 is false.
(aryl halides do not undergo nucleophilic substitution under ordinary conditions).
Statement - 2 is correct.
The carbon-halogen bond in aryl halides have partial double bond character so it becomes shorter and stronger and cannot be easily replaced by nucleophiles.
So, Statement - 1 is false; Statement - 2 is true
Hence d is the correct answer.
