The Attempt at a Solution

There were 4 parts to find net capacitance across AD, FE, AE and AO

I need help with AO and i don't have any idea how to do it

Hi cupid.callin...

We know that B,F and C,E are at the same potential...So by drawing a simplified diagram of the problem (With A and O at the ends) i do come to an answer (which is not a good looking one!)...So you can go ahead like that...
