The correct option is B Exodermis
Epidermal tissues are the outer protective tissue. These are generally present in layers of the epidermis, hypodermis, and the endodermis. The outermost layer of cells in the plant cortex, lying immediately below the epidermis is the hypodermis which is also known as exodermis. These cells are sometimes modified to give additional structural support or to store food materials or water. Thus, option C is correct.
