The capacitance of a parallel plate capacitor is` C_(a)` (Fig. a). A dielectric of dielectric constant K is inserted as shown in fig. (b) and (c). If `C_(b)` and `C_(c)` denote the capacitances in fig. (b) and (c), then

A

both` C_(b), C_(c) gt C_(a)`

B

`C_(c) gt C_(a) "while" C_(b) gt C_(a)`

C

both `C_(b), C_(c) lt C_(a) `

D

`C_(a) = C_(b) = C_(c) `
