Explanation :
Given that a circuit contains only a capacitor and a battery. The capacitance of a parallel plate capacitor is given as :
[tex]C=\dfrac{A\epsilon_0}{d}[/tex]
Where,
A is the area of the plates
d is the distance between the plates
[tex]\epsilon_0[/tex] is the permittivity of the dielectric
If the distance between the plates of the capacitor is decreased, the capacitance of the capacitor will increase.
Hence, the correct option is (B) "The capacitance of the capacitor will increase".
