Waxy layer that covers the surface of the leaf and reduces water loss:
A
Stoma
B
Epidermis
C
Veins
D
Cuticle
Explanation: 

Detailed explanation-1: -A waxy layer known as the cuticle covers the leaves of all plant species. The cuticle reduces the rate of water loss from the leaf surface. Other leaves may have small hairs (trichomes) on the leaf surface.

Detailed explanation-2: -Answer: The waxy covering on plant leaves, young stems, and fruit is called the “cuticle".

Detailed explanation-3: -Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots). Dermal tissue of the stems and leaves is covered by a waxy cuticle that prevents evaporative water loss.

Detailed explanation-4: -The Cuticle and Upper Epidermis Just like our skin helps protect us, leaves have an outer layer that protects them. This outermost layer is called the cuticle. It is generally waxy to protect the leaf and prevent water loss.

Detailed explanation-5: -Thick waxy cuticle: The cuticle cuts down water loss in two ways: it acts as a barrier to evaporation and also the shiny surface reflects heat and so lowers temperature. Sunken stomata: Stomata may be sunk in pits in the epidermis; moist air trapped here lengthens the diffusion pathway and reduces evaporation rate.
