Epidermal layer found only in thick skin.
A
stratum basale
B
stratum spinosum
C
stratum lucidum
D
stratum corneum
Explanation: 

Detailed explanation-1: -Stratum lucidum, 2-3 cell layers, present in thicker skin found in the palms and soles, is a thin clear layer consisting of eleidin which is a transformation product of keratohyalin.

Detailed explanation-2: -Only thick skin contains the stratum lucidum layer. The stratum lucidum is a thin, transparent layer consisting of two to three layers of cells. It contains a protein called eleidin.

Detailed explanation-3: -The stratum lucidum is a smooth, seemingly translucent layer of the epidermis located just above the stratum granulosum and below the stratum corneum. This thin layer of cells is found only in the thick skin of the palms, soles, and digits.

Detailed explanation-4: -Its presence indicates the importance of having thicker skin to protect against frequent exposure to mechanical stress. The stratum lucidum is found in in between the stratum corneum and the stratum granulosum. The keratinocytes are filled with eleidin (a protein that may be later converted to keratin).

Detailed explanation-5: -There are only four layers in the epidermis of thin skin. The stratum lucidum layer is absent.
