E Eventually, the process approaches a steady state. In that steady state, the charge of the capacitor is not changing. What is the current in the circuit in the steady state?
F In the steady state, what is the charge of the capacitor?

Initially capacitor is shorted. Hence the voltage across capacitor will be zero. The current emerges from positive terminal of the battery, hence the current will be clockwise. In steady state, the capacitor is fully charged and no current flows through the circuit. In steady-state the voltage across capacitor is equal to voltage across battery.
