Solution

The correct option is D $P_{2} O_{5}$
Benzamide can be converted into Benzonitrile by $P_{2} O_{5}$ as follows:

$C_{6} H_{5} C O N H_{2} P_{2} O_{5} - -- \to C_{6} H_{5} C N$

by eliminating $H_{2} O$ molecule as $P_{2} O_{5}$ is powerful dehydrating agent.

Option D is the correct answer
