Answer» Correct option is (a) [M^-1L^-3T^4I^2] Explanation: εo is the absolute permittivity of AIR medium and has VALUE 8.854*10^-12C^2N^-1m^-2. Its dimension is [M^-1L^-3T^4I^2]. The permittivity of a medium is the product of this TERM with the dielectric constant or RELATIVE permittivity of that medium.
