Solution

The correct option is C
esters

Soaps are prepared by alkaline hydrolysis of esters. The process is known as saponification. In this process the esters react with a base to give back the alcohol and salt of carboxylic acid. For example:

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