Four identical capacitors each of capacitance C are arranged as shown in the figure. What is the effective capacitance between P and Q?

$\frac{5C}{3}$

The correct answer is Option (2) → $\frac{3C}{5}$

$C_1$ and $C_2$ are in parallel.

Their combination is in series with $C_3$

This whole setup is in parallel with $C_4$

The correct answer is $\frac{5C}{3}$
