Solution

The correct option is B Statement 1 is True, statement 2 is True; statement 2 is not a correct explanation for statement 1.
Bond angle in $P F_{3}$ greater than the bond angle in $P H_{3}$ due to steric crowding as the size of $F$ is larger than the size of $H$ .

Electrons in $P F_{3}$ are displaced towards more electro-negative $F$ , in $P - F$ bond.

Hence, Statement 1 is True, statement 2 is True; statement 2 is not a correct explanation for statement 1.
