A parallel plate capacitor with air as the dielectric has capacitance C. A slab of dielectric constant K and having the same thickness as the separation between plates is introduced so as to fill one-fourth of the capacitor as shown in the figure. The new capacitance will be :

`(K+3)C/4`

`(K+2)C/4`

`(K+1)C/4`

`(KC)/4`
