The correct expression for the instantaneous current if instantaneous voltage is Vm(sint) in an inductive circuit is?

The correct expression for the instantaneous current if instantaneous voltage is Vm(sint) in an inductive circuit is? Correct Answer i = -Vm(cost)/XL

V=Vm*sint I=V/XL = -Vm(cost)/XL (since current lags voltage by 900 in inductive circuit).
