Solution

The correct option is A i - e, ii - d, iii - b, iv - c, v - a
Outermost thick protective layer of the leaf is caller upper epidermis. It secretes cuticle which prevents the excess loss of water from the plants.
Below upper epidermis there are cells specialised for photosynthesis called mesophyll cells.
Just like upper epidermis, thick protective layer is present on the lower surface called lower epidermis.
Tiny pores present on the surface of the leaf are called stomata.
