Solution

The correct option is B $C_{2} H_{2}$
When calcium carbide reacts with water-

$C a C_{2} + 2 H_{2} O \to C a (O H)_{2} + C_{2} H_{2}$

The product formed is calcium hydroxide and ethyne.

This is the laboratory method for preparation of alkyne from calcium carbide.

Hence, option $C$ is correct.
