Consider elastic collision of a particle of mass m moving with a velocity u with another particle of the same mass at rest. After the collision the projectile and the struck particle move in directions making angles

\theta_{1}

and

\theta_{2}

respectively with the initial direction of motion. The sum of the angles

\theta_{1}+\theta_{2},

is :

Options

A $45^{\circ}$
B $90^{\circ}$
C $135^{\circ}$
D $180^{\circ}$
