The final product [B] is :

Cyclohexylmethylamine reacts with benzoyl chloride under basic conditions to form amide [A]:
cyclohexylmethyl benzoamide.
LiAlH₄ reduces the amide carbonyl to CH₂, converting the N-benzoyl group to a benzyl group.
The product [B] is a secondary amine formed by reduction:
cyclohexylmethyl-benzylamine ($C_6H_{11}-CH_2-NH-CH_2-C_6H_5$).
This structure contains secondary amine (N-H) with two carbon substituents: cyclohexylmethyl and benzyl groups.
