HI- When you apply deltaV at the gate, since you have shorted source you will gm*deltav flowing into the transistor, This will be divided and flow into rO and rD, so find current flowing into Rd which is gm*Ro*deltaV/(R0+Rd).
Please note that short circuit current is same as current flowing through Rd.
If you don't understand this please use simple KVL and KCL, you will the same answer.
Best Regards, Raj.
