which letter indicates cells that produce melanin in the hair root?
a
b
c
d
e

Explanation:

To determine which letter indicates cells that produce melanin in the hair root, we recall that melanocytes (cells producing melanin) are associated with the hair matrix or surrounding regions. In hair root anatomy, the cells producing melanin (melanocytes) are typically near the hair bulb. Analyzing the options:

• A: Likely the hair shaft or outer structure, not melanin - producing.
• B: Maybe the inner root sheath, not melanin - producing.
• C: Not the typical melanin - producing region.
• D: The hair matrix region where melanocytes (or associated cells) produce melanin for hair pigmentation.
• E: Likely connective tissue or other, not melanin - producing.

So the correct letter is D.

Answer:

D
