(D) Step $1$: The reaction of ethyl $2$-(cyanomethyl)benzoate with $H_2/Ni$ leads to the reduction of the nitrile group $(-CN)$ to a primary amine $(-CH_2NH_2)$.Step $2$: The resulting amino ester undergoes intramolecular cyclization to form a cyclic amide (lactam),specifically $3,4$-dihydroisoquinolin-$1(2H)$-one.Step $3$: The subsequent reaction with $DIBAL-H$ (diisobutylaluminium hydride) reduces the amide carbonyl group to an imine,resulting in $3,4$-dihydroisoquinoline as the final major product.

The major product of the following reaction is:
