Stratum Spinosum
B
Stratum Basale

E
Stratum Corneum
Explanation: 

Detailed explanation-1: -Melanocytes are derived from neural crest cells and primarily produce melanin, which is responsible for the pigment of the skin. They are found between cells of stratum basale and produce melanin. UVB light stimulates melanin secretion which is protective against UV radiation, acting as a built-in sunscreen.

Detailed explanation-2: -The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells. The basal cell layer contains cells called melanocytes.

Detailed explanation-3: -This layer also contains melanocytes. Stratum spinosum, 8-10 cell layers, also known as the prickle cell layer contains irregular, polyhedral cells with cytoplasmic processes, sometimes called “spines”, that extend outward and contact neighboring cells by desmosomes.
