INCORRECT!

Type of reaction

This is a Friedel-Crafts acylation, which is a type of electrophilic aromatic substitution that occurs on aromatic rings that are not strongly deactivated.

Position of attack

The methyl group directs the attack ortho/para, so this product (from para attack) is substituted at the correct position.

Position of C=O

The product of acylation should have the carbonyl C=O next to the ring. This is because this group becomes the electrophile that attacks the ring. The product A shown would need the methyl end of the chain to react as electrophile - very unlikely!
