The charge stored by the capacitor in the given circuit in the steady state is \hspace{1cm} C.

Correct answer:C
Standard Method
Given: The capacitor is in a resistive circuit connected to a source of . The capacitance is .
Find: The charge stored on the capacitor in steady state.
In steady state, no current flows through the capacitor branch, so the capacitor behaves as an open circuit. The remaining network is treated as a potential divider bridge.
Potential at the left node is
Potential at the right node is
Therefore, the potential difference across the capacitor is
Now use
So,
Therefore, the charge stored by the capacitor is . The correct option is C.
Treating the capacitor as a short circuit in steady state is wrong because for a DC circuit after a long time, no current flows through the capacitor branch. Treat it as an open circuit before finding the terminal potential difference.
Using the battery voltage directly across the capacitor is wrong because the capacitor is connected between two internal nodes of the bridge, not directly across the source. First find the potentials of both nodes, then take their difference.
Applying the potential divider ratio with the wrong resistor in the numerator is a common error. The node potential must be found using the resistor segment corresponding to that node in the divider branch.
