Solution

The correct option is A Displacement Reactions
Sodium metal $(N a)$ reacts with ethanol ( $C_{2} H_{5} O H$ ) to produce sodium ethoxide ( $C_{2} H_{5} O N a$ ) and hydrogen ( $H_{2}$ ). It is a displacement reaction in which the more active sodium displaces hydrogen in ethanol. The equation can be written as:
$2 N a + 2 C_{2} H_{5} O H \to 2 C_{2} H_{5} O N a + H_{2}$
