Solution

The correct option is A $C H_{3} C O O H$ and $C_{2} H_{5} O H$

$C H_{3} C O O H A + 2 N a \to 2 C H_{3} C O O N a + H_{2}$

$C_{2} H_{5} O H B + N a \to C H_{3} - C H_{2} - O N a + H_{2}$

$C H_{3} C O O H + N a O H \to C H_{3} C O O N a + H_{2} O$

$C H_{3} C O O H + C_{2} H_{5} O H H_{3} O^{+} - --- \to c a t a l y s t C H_{3} C O O C_{2} H_{5} a pleasant smelling compound + H_{2} O$

Option A is correct.
