A body of mass `1 kg` begins to move under the action of a time dependent force `vec F = (2 t hat I + 3 t^(2) hat j) N`, where `hat i` and `hat j` are unit vectors along x-and y-axes. What power will be developed by the force at the time `t` ?

A

`(2t^(2)+3t^(3))W`

B

`(2t^(2)+4t^(4))W`

C

`(2t^(3)+3t^(4))W`

D
