Four metallic plates each with a surface area of one side A, are placed at a distance d from each other. The two outer plates are connected to one point A and the two other inner plates to another point B as shown in the figure. Then the capacitance of the system is–

A

ε0 A d\frac { \varepsilon _ { 0 } \mathrm {~A} } { \mathrm {~d} }

B

C

3ε0 A d\frac { 3 \varepsilon _ { 0 } \mathrm {~A} } { \mathrm {~d} }

D
