The cork cambium or phellogen cells divide periclinal cutting off cells towards the outside and inside. The cells cut off towards the outside become suberised and dead. These are compactly packed in radial rows without intercellular spaces and form cork or phellem.

Cork is impervious to water due to the suberin and provides protection to underlying tissues. The cells cut off from cork cambium towards the inside add to the cortex and are called secondary cortex cells of phelloderm cells. Hence, the correct answer is option 2.
