B. Capacitance value decreases
C. Capacitance value remains same
D. Capacitance value becomes zero

Right Answer is: A
SOLUTION
Capacitor consists of two plates of a conductor and a dielectric insulator between them
\(C = \frac{{\epsilon A}}{d}\)
Where
C = capacitance in farads
ϵ = Permittivity of dielectric
A = area of plate overlap in square meters
d = distance between plates in meters
C ∝ dielectric constant
If the dielectric constant of the material of the capacitor is increased, then the value of capacitance also increases.
