A balloon rises up (initial velocity is zero) with constant net acceleration of $10 m/s^2$.  After 2 seconds a body drops from the balloon. After further 2 seconds match the  Column-I with Column-II. (g =$10 m/s^2$)

Column-I		Column-II
A)	Height of body from the ground	p)	Zero
B)	Speed of the body	q)	10 SI units
C)	Displacement of the body in 2s after it drops from the balloon	r)	40 SI units
D)	Acceleration of the body	s)	20 SI units
