A projectile is fired with velocity u at an angle `theta` with horizontal. At the highest point of its trajectory, it splits up into three segments of masses m, m and 2m. First part falls vertically downward with zero initial velocity and second part returns via same path to the point of projection. The velocity of third part of mass 2 m just after explosion will be

`u cos theta`

B

`(3)/(2) u cos theta`

C

`2u cos theta`
