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 angle `theta_1` and `theta_2` respectively with the initial direction of motion. The sum of the angles `theta_1 + theta_2` is :

A

`45^@`

B

`90^@`

C

`135^@`
