Question

Keratinocytes comprise what percentage of epidermal cells?
(A) Keratinocytes comprise 95% of epidermal cells
(B) Keratinocytes comprise 90% of epidermal cells
(C) Keratinocytes comprise 80% to 99% of epidermal cells
(D) Keratinocytes comprise 50% to 60% of epidermal cells
(E) Keratinocytes comprise 55% of epidermal cells
Choose the most appropriate answer from the options given below:

• A. A and C only
• B. B and C only
• C. A only
• D. E only

Hint:

Remember — Keratinocytes make up about 90–95% of the epidermis.

Answer 1

The Correct Option is A

Keratinocytes are the primary cell type in the epidermis and make up the vast majority of epidermal cells.
Studies generally agree that keratinocytes account for around 90% to 95% of all epidermal cells.
Therefore, statements (A) and (C) are within the accepted range.
Statements (B), (D), and (E) underestimate the percentage or provide less common figures.
So, the correct answer is A and C only.
