The major product of the following reaction is:

Match List $-I$ with List $-II.$

List $-I$ (Products formed)	List $-II$ (Reaction of carbonyl compound with)
$(a).$ Cyanohydrin	$(i).$ $NH_2OH$
$(b).$ Acetal	$(ii).$ $RNH_2$
$(c).$ Schiff's base	$(iii).$ Alcohol
$(d).$ Oxime	$(iv).$ $HCN$

Choose the correct answer from the options given below:

Match the following:

$A$. Lucas reagent	$I$. $SnCl_2 + HCl$
$B$. Clemmensen reagent	$II$. $[Ag(NH_3)_2]^+$
$C$. Tollen's reagent	$III$. Anhydrous $ZnCl_2 + conc. HCl$
$D$. Stephen reagent	$IV$. $Zn-Hg/HCl$

The product $(P)$ formed in the following reaction is $:$
