4 μF

Explanation:

The two 2 μF capacitors are in parallel, so they can be replaced by their equivalent capacitance of 4 μF.

This leaves us with two parallel branches, each having two 4 μF capacitors in series.

The capacitance of each branch is 4 μF×4 μF4 μF+4 μF=2 μF.

So, finally we have two 2 μF capacitors in parallel, leading to an overall equivalent capacitance of 4 μF

Note
For two capacitors C1 and C2 in series, the equivalent capacitance is C1C2C1+C2, while the equivalent of parallel capacitors is C1+C2
