The ratio between the electric flux density in a dielectric medium and the corresponding electric field strengthis called-

Correct option is C

Electric flux density (D): Represents the amount of electric flux passing through a unit area of a surface.

Electric field strength (E): Measures the force exerted on a unit positive charge placed in an electric field.

Permittivity (ε): Represents the ability of a dielectric material to store electrical energy, and it is the ratio of electric flux density to electric field strength.
