Solution

The correct option is C (A)-(ii) (B)-(i) (C)-(iv) (D)-(iii)
Clemmensen reduction:ZnHg+conc.HCl
Clemmensen reduction reduces Aldehydes and ketones to corresponding hydrocarbons.

Wolff-kishner: NH2NH2,KOH/
It reduces aldehydes and ketones to corresponding hydrocarbons.

Iodoform reaction : I2+NaOH
Iodoform reaction used for the identifiacation of methyl ketone.

Catalytic hydrogenation: H2,Pd/Pt/Ni
It reduces alkene to alkane and aldehyde and ketones to alcohols.

Hence, the correct answer is option (c).
