5

The correct option is D:

Explanation of the correct option

1. A cell separates into two identical daughter cells during mitosis, which repeats all of its components, including its chromosomes.
2. After n mitotic divisions 2ⁿ cells are produced.
3. Therefore, a single cell requires 5 mitotic divisions to produce 32 cells.

Explanation of the incorrect options

Option A

1. A cell can produce 65,536 cells after 16 mitotic divisions.

Option B

1. A cell creates 256 cells after 8 mitotic divisions.

Option C

1. When a cell undergoes 4 mitotic divisions, it produces 16 cells.

Final answer:

To create 32 cells, a single cell has to go through 5 mitotic divisions.
