Given below are two statements:
Assertion (A): Alkyl benzene is not prepared by Friedel-Crafts alkylation of benzene. 
Reason (R): Alkyl halides are less reactive than acyl halides in the Friedel-Crafts reaction
 
1. Both (A) and (R) are True, and (R) is the correct explanation of (A).
2. Both (A) and (R) are True, but (R) is not the correct explanation of (A).
3. Both (A) and (R) are False.
4. (A) is True, but (R) is False.
