The correct answer is: $1 \mu \mathrm{F}$
The given network can be simplified as shown in following figure


The equivalent capacitance between $P$ and $Q$ is given by
$$
\begin{aligned}
& \frac{1}{C_{\text {eq }}}=\frac{1}{3}+\frac{1}{3}+\frac{1}{3}=1 \mu \mathrm{F} \\
& C_{\text {eq }}=1 \mu \mathrm{F}
\end{aligned}
$$
