In a parallel plate capacitor, the separation between the plates is 3mm with air between them. Now a 1mm thick layer of a material of dielectric constant 2 is introduced between the plates due to which the capacity increases. In order to bring its capacity of the original value, the separation between the plates must be made-

A

`1.5 mm`

B

`2.5 mm`

C

`3.5 mm`

D

`4.5 mm`
