Solution

The correct option is D Assertion is incorrect but Reason is correct.
Ethyl chloride reacts with sodium ethoxide to from diethyl ether. Here ethoxide ion behaves as strong nucleophile. It displaces chloride ion from ethyl chloride.

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

Ethanol is a Bronsted acid and lewis base.

Thus, assertion is incorrect but Reason is correct.

Hence, option $D$ is the answer.
