A parallel plate capacitor of capacitance 20 $\mu$F is being charged by a voltage source whose potential is changing at the rate of 3 V/s. The conduction current through the connecting wires, and the displacement current through the plates of the capacitor, would be, respectively.

(1) Zero, 60 $\mu$A

(2) 60 $\mu$A, 60 $\mu$A

(3) 60 $\mu$A, zero

(4) Zero, zero

(1) Zero, 60 $\mu$A

(2) 60 $\mu$A, 60 $\mu$A

(3) 60 $\mu$A, zero

(4) Zero, zero
