[B]. discharging
[C]. fully charged
[D]. fully discharged

Answer: Option C

When fully charged, act as open circuit so for open circuit voltage across resistor will be zero.

How ? even fully charged the voltage still prevails. Please explain.

Uncharged capacitor acts as a short to current initially and after fully charged it acts as an open in the circuit.

So no voltage is zero across the series connected resistor because there is no current.
