Right choice is (b) False

Explanation: Concentration polarization refers to the electrochemical reaction that is controlled by the diffusion of ions in an electrolyte. This occurs in the low concentration of electrolyte. It is neglected in the case of anodic reaction (metal dissolution) because there is a sufficient supply of metal atoms in a metallic piece and there is no need for diffusion.
