Answer #1

We know that for capacitors in series the current hence the charge remains the same. On the other hand, for parallel circuit, the voltage is the same. Since capacitors 1 and 2 and then 3 and 4 are in series hence the charge across 1 and 2 are equal and then 3 and 4 are equal. Hence I and IV are correct.
Also as the combination of capacitors 1 and 2 is parallel to the combination of capacitor 3 and 4, it must be equal to the EMF of the battery. So III is also correct.

I, III, IV are correct.
