A projectile is fixed on a horizontal ground. Coefficient of restitution between the projectile and the ground is 'e'. If `a,b` and `c` be the ration of time of flight `[(T_(1))/(T_(2))]`, maximum height `[(H_(1))/(H_(2))]` and horizontal range `[(R_(1))/(R_(2))]` in first two collisions with the ground, then a, b and c in terms of 'e' will be

A

`a=(1)/(e )`

B

`b=(1)/(e^(2))`

C

`c=(1)/(e^(2))`

D

all of the above
