Solution

The correct options are
A $(C H_{3} C O)_{2} O$
B $C H_{3} C O C l$
C $C H_{3} C O O C_{2} H_{5}$
On reaction with $L i A l H_{4}$ , acid anhydrides, acid chlorides and esters are reduced to corresponding alcohol but amides are reduced to amines.
The reactions take place as:

A) $(C H_{3} C O)_{2} O \to 2 C H_{3} C H_{2} O H$

B) $C H_{3} C O C l \to C H_{3} C H_{2} O H$

C) $C H_{3} C O N H_{2} \to C H_{3} C H_{2} N H_{2}$

D) $C H_{3} C O O C_{2} H_{5} \to 2 C H_{3} C H_{2} O H$

Options A, B and D are correct.
