`overset(NaBH_(4))(leftarrow) PhCH=CH-CHOunderset(2. H_(3)O^(+))overset(1. LAH, ether)(rarr)(A)` The products `(A)` and `(B)` are:A. a.B. b.C. c.D. d.

Answer» Correct Answer - D
`LAH` reduces `(CHO)` group to `(CH_(2)OH)` and also reduces double bond when `Ph` group is attached to `beta`-position of double bond, whereas `NaBH_(4)` reduces only `(-CHO)` group to `(CH_(2)OH)` group. So the answer is `(d)`.
