Answer:
A
Explanation:
<em>The active state of cell division covers the prophase, metaphase, anaphase, and telophase. The total number of observed cells that were undergoing cell division can, thus, be calculated by adding the number of cells in each stage of the cell division.</em>
Total number of cell in division = 20+4+2+4
= 30
Probability that a randomly chose cell will be undergoing cell division = <em>number of cells in division/total number of cells</em>
= 30/200
= 0.15 or 15%
The correct option is, therefore, A.
