A parallel plate capacitor having a separation between the plates d, plate area A and material with dielectric constant K has capacitance C0. Now one-third of the material is replaced by another material with dielectric constant 2K, so that effectively there are two capacitors one with area 31A , dielectric constant 2K and another with area 32A and dielectric constant K. If the capacitance of this new capacitor is C then C0C is
a. 1
b. 34
c. 32
d. 31
