A diode circuit is so arranged that when the switch is ___

A diode circuit is so arranged that when the switch is open it’s KVL gives

Ri+ 1/C ∫i dt = 0
When the switch is closed,
Ri+ 1/C ∫i dt = Vs
Vs is the dc supply voltage.

The diode is so connected that it is forward biased when switch is closed

The circuit is mostly likely be a

A. diode in parallel with Vs, switch, R & C
B. diode in series with R, than parallel with Vs & C
C. diode in series with the switch, R, C & Vs
D. diode in series with R,C & Vs with the switch connected in parallel across Vs
