Correct answer

C. Phellem

Step-by-step solution

Cork cambium undergoes periclinal division and cuts off thick walled suberised dead cork cells towards outside and it cuts off thin walled living cells i.e., phelloderm on an inner side.

Collenchyma is called as living, mechanical, simple permanent tissue.
