The equivalent capacitance of the combination shown in the figure is :
Answer: (C) $2C$
Both plates of the middle capacitor are connected, by plain wires, to the right-hand junction. It is short-circuited and stores no charge.
The remaining two capacitors $C$ are in parallel between the two terminals:
$$C_{eq} = C + C = 2C$$
