A parallel plate condenser is filled with two dielectrics as shown. Area of each plate is `A "metre"^(2)` and the separtion is `t` metre. The dielectric constants are `K_(1)` and `K_(2)`, respectively. Its capacitance in farad will be

A

`(epsi_(0)A)/t(k_(1)+k_(2))`

B

`(epsi_(0)A)/t.(k_(1)+k_(2))/(2)`

C

`(2epsi_(0)A)/t(k_(1)+k_(2))`

D

`(epsi_(0)A)/t.(k_(1)+k_(2))/(2)`
