A solid uniform sphere rotating about it...

A solid uniform sphere rotating about its axis with kinetic energy `E_(1)` is gently placed on a rough horizontal plane at time t=0, Assume that, at time `t=t_(1)`, it starts pure rolling and at that instant total KE of the sphere is `E_(2).` After sometime, at time `t=t_(2)`. KE of the sphere is `E_(3)`. Then

A

`E_(1)=E_(2)=E_(3)`

B

`E_(1)gtE_(2)=E_(3)`

C

`E_(1)gtE_(2)gtE_(3)`

D
