The correct answer is: $45 \mu \mathrm{C}$
$\begin{aligned} & \text { In steady state, } i=\frac{9}{27 \times 10^3} \\ & V_c=I \times R=\frac{9}{27 \times 10^3} \times 15 \times 10^3=5 \mathrm{~V} \\ & q=C V_c=9 \times 10^{-6} \times 5 \\ & q=45 \times 10^{-6} \mathrm{C}=45 \mu \mathrm{C}\end{aligned}$
