Four metallic plates each of surface area (of one side) $A$, are placed at a distance $d$ apart from each other. The two outer plates are connected to a point $P$ and the two inner plates are connected to another point as shown in figure below. Then, the capacitance of the system is
  • A$\varepsilon_0 \frac{A}{2 d}$
  • B$\varepsilon_0 \frac{A}{d}$
  • C$2 \varepsilon_{0} \frac{A}{d}$
  • D $3 \varepsilon_{0} \frac{A}{d}$
