Equivalent Capacitance: Distinguishing Parallel/Series

[PNGeng]

Homework Statement

I'm having trouble distinguishing exactly which combinations are in parallel and which are in series. The fact that both ends of the circuit are open is throwing me off. Can someone walk me through this?

Open ends means that no current can flow there and so no influence on the circuit. Just remove any dangling components.

Got it, thanks!
