Solution

The correct option is C All of them reach the ground with same speed.
Vertical component of initial velocities are different reach the ground at different time.

When a body is projected from top of the building of height H,
from equations of motion,
|v|2|u|2=2g.S
|v|2|u|2=2g.|S|cosθ
|v|2|u|2=2g.H
|v|=|u|2+2g.H
Speed of the body when it reaches ground is same for all the bodies, irrespective of angle of projection.
