  3. P — Stratum corneum, Q — Germinative layer
  4. P — Granular layer, Q — Cornified layer
Answer

P — Stratum corneum, Q — Germinative layer

Reason — Keratin is a fibrous structural protein that provides protection and waterproofing to the skin. It is found in the stratum corneum, the outermost layer of the epidermis, made up of dead, keratinized cells.
Melanin is the pigment responsible for skin color and UV protection. It is present in the germinative layer, the innermost layer of the epidermis.
