The equivalent capacitance of the combination shown is
Answer: (A) $2C$
The top and bottom rails are both joined to the right terminal, so they are the same node. The two vertical capacitors therefore have both plates at the same potential and hold no charge.
The two horizontal capacitors are in parallel between the terminals: $C_{eq}=2C$.
