Solution

Verified by Toppr

Correct option is B)

The oxoacid of phosphorus with the highest number of $P - H$ bond will be the strongest reducing agent.
Here $H_{3} P O_{2}$ contain two $P - H$ bond which highest among all the given oxoacids of phosphorus.
Thus $H_{3} P O - 2$ is the strongest reducing agent among the given oxoacids of phosphorus.
