The dielectric constant (k) is defined as the ratio of the permittivity of a substance to the permittivity of free space. It is a dimensionless quantity and has no units or dimensional formula. Options A and D are incorrect as they provide the dimensional formula of permittivity of free space and electric permittivity of free space respectively. Option B is incorrect as it provides the dimensional formula of electric current density.
