Three plates A, B and C are placed close to each other with `+Q` charge given to the middle plate. The inner surfaces to A and C can be connected to earth through plate D and keys `K_(1)` and `K_(2)` . The plates D is a dielectric slab with dielectric constant `K_(1)` then the charge that will flow through plate D and keys `K_(1)` and `K_(2)` . The plate D is a dielectric slab with dielectric constant K , when both the keys are closed, charge that will flow through key `K_(1)` will be :
,

A

`(t)/((d+t))Q`

B

`(d)/((d+t))Q`

C

`((d+t))/(t)Q`

D
