Solution

The correct option is A The impulsive reaction of wall is $2 m V sin α$
The initial Momentum,

$P i = m V s i n α$

The final momentum is,

$P_{f} = - m V s i n α$

The negative sign shows only the direction of the velocity of the particle after the collision.
The impulse force is equal to change in momentum

$f_{i} = Δ P = P_{f} - P_{i}$

$| f_{i} | = 2 m V s i n α$

The correct option is A.
