A parallel plate capacitor is to be designed, using a dielectric of dielectric constant 5, so as to have a dielectric strength of `10^(9) Vcdotm^(-1)`. If the votage rating of the capacitor is 12 kV, the minimum area of each plate required to have a capacitance of 80 pF is

C. `25.0 xx 10^(-5) m^(2)`
D. `12.5 xx 10^(-5) m^(2)`
