(B) Cork cells,also known as phellem,are formed during secondary growth in plants.These cells have thick walls that are impregnated with a waxy,hydrophobic substance called $Suberin$.$Suberin$ deposition makes the cell walls impervious to water and gases,which protects the inner tissues of the plant from desiccation and mechanical injury.
