• A. Lower epidermis
• B. Upper epidermis
• C. Both of (A) and (B)
• D. Petiole

Answer 1

The correct option is C Both of (A) and (B)

In an unifacial leaf, the stomata are present in lower and upper epidermis. Unifacial leaf is also called as isobilateral or amphistomatic. Unifacial leaf is a leaf that develops from one side of the leaf primordium only and in consequence has only an encircling adaxial or abaxial epidermis (may be secondarily flattened and appear dorsiventral).
Thus, the correct answer is option C.
