During which phase of mitosis do the chromatids become chromosomes? a. telophase. b. anaphase. c. prophase. d. metaphase

Option B, Anaphase

Explanation:

Prophase is the first stage of cell division. In this phase the chromosomes become coiled and hence are more clearly visible in this stage under a light microscope. Also the nuclear envelope disappears.

In the metaphase, the chromosome arranges them along the metaphase plate. This is an imaginary line of alignment.  

In anaphase, the dyad (pair of chromosomes) or sister chromatids are pull apart and hence separated into two individual chromosomes.  

Telophase is the last stage of cell division in which the two daughter cells are formed.  

Hence, option B is correct
