The condensation of the chromosomes is maximal with visible centromeres at which phase of cell cycle ?

The correct option is D M phase
The cell cycle is defined as the production of daughter cell from a cell through series of divisions. There are four events:

G1 phase or the gap phase there will be no division. But the day to day function takes place.

S-phase is the synthetic phase where the replication of DNA takes place.

G2 phase: In this phase, the cell prepares for cell division.

Then the M phase or the mitotic phase where there is a cell division takes place. In the sub phase called as metaphase, there will be maximum condensation and the chromatins are arranged in a row.
