The image shows chromosomes that have condensed and align along the central plane of the cell, forming what is commonly called the metaphase plate.

Option: prophase – In prophase, chromosomes condense and become visible, but they are not yet lined up at the center; the nuclear envelope begins to break down and spindle apparatus forms.

Option: metaphase – Here, chromosomes align midway between the two poles with sister chromatids held together at the centromeres and kinetochore microtubules attaching them to opposite spindle poles, producing the characteristic metaphase plate.

Option: interphase – Interphase is the cell cycle phase when the cell grows and DNA is replicated; chromosomes are not condensed into visible sister chromatids and there is no metaphase plate.

Option: anaphase – In anaphase, sister chromatids separate and are pulled toward opposite poles, resulting in movement away from the center rather than alignment at the center.

Option: telophase – Telophase involves the arrival of chromosomes at the poles, de-condensation begins, and the nuclear envelope re-forms; the chromosomes are no longer at the metaphase plate.

Taken together, the visual cue of chromosomes neatly lined up at the cell’s equator corresponds to the metaphase stage, as opposed to the other mitotic stages described above.
