The I.L.T of Vc(s), i.e Vc(t)=sint after that differentiate we will get cost and putting the value .then we got an answer is 0.5 A.

You are right @Mohsin.
But initially it is sin term I mean just check the Laplace transform.

1/(s2+1) is sinθ so after differentiation it is cosθ.

No, it is wrong because when we take the derivative of cos the answer will become sin and sin0 is 0 so in my opinion answer is 0. Option A.
