Options:
  • A
    No charge flows in (a) but charge flows from $R$ to $L$ in (b)
  • B
    Charges flow from $L$ to $R$ in both (a) and (b)
  • C
    Charges flow from $R$ to $L$ in (a) and from $L$ to $R$ in (b)
  • D
    No charge flows in (a) but charge flows from $L$ to $R$ in (b)

The correct answer is:
Charges flow from $R$ to $L$ in (a) and from $L$ to $R$ in (b)
Charge (or current) always flows from higher potential to lower potential.
Potential $=\frac{\text { Charge }}{\text { Capacitance }}$
