a) eleidin produced by merkel cell
b) melanin produced by melanocyte
c) keratohyalin produced by basal cell
d) cytokine produced by langerhans cell

Explanation:

Melanocytes produce melanin which acts as a natural sunscreen, absorbing UV - light and protecting keratinocytes' nuclear DNA from damage. Eleidin is related to keratinization and not for UV - protection. Keratohyalin is involved in keratin filament aggregation and not UV - shielding. Cytokines from Langerhans cells are part of the immune response and not for UV - protection.

Answer:

B. Melanin produced by melanocyte
