Match the reactions given in Column-$I$ with the suitable reagents given in Column-$II$.

Column-$I$ (Reactions)	Column-$II$ (Reagents)
$(A).$ Benzophenone $\to$ Diphenylmethane	$(1).$ $LiAlH_4$
$(B).$ Benzaldehyde $\to$ $1-$Phenylethanol	$(2).$ $DiBAL-H$
$(C).$ Cyclohexanone $\to$ Cyclohexanol	$(3).$ $Zn(Hg) / \text{Conc. } HCl$
$(D).$ Phenyl benzoate $\to$ Benzaldehyde	$(4).$ $CH_3MgBr$

(A-3, B-4, C-1, D-2) $(A)-3, (B)-4, (C)-1, (D)-2$
Step-by-step explanation:
$(A).$ Benzophenone $(Ph_2C=O)$ is reduced to Diphenylmethane $(Ph_2CH_2)$ using Clemmensen reduction,which uses $Zn(Hg) / \text{Conc. } HCl$ (Reagent $3$).
$(B).$ Benzaldehyde $(PhCHO)$ reacts with Grignard reagent $CH_3MgBr$ (Reagent $4$) followed by hydrolysis to form $1-$Phenylethanol $(PhCH(OH)CH_3)$.
$(C).$ Cyclohexanone is reduced to Cyclohexanol using $LiAlH_4$ (Reagent $1$).
$(D).$ Phenyl benzoate is reduced to Benzaldehyde using $DiBAL-H$ (Reagent $2$).
