Solution
The correct option is A Metaphase
Prophase is the stage of mitosis, which is characterized by spindle formation, shortening and thickening of chromosomes, the disintegration of the nuclear envelope and disappearance of the nucleolus.
Metaphase proceeds prophase and is marked by the movement of chromosomes towards the equator of cell mediated by kinetochore microtubules of spindle fibres. Alignment of chromosomes on the equatorial plane of the spindle, the metaphase plate, marks the end of metaphase.
Anaphase is the stage of mitosis which is characterized by separation of sister chromatids followed by their movement towards the opposite pole of the spindle.
Completion of separation of sister chromatids, which are now present at the opposite poles of cell marks telophase. The cell resumes the interphase state during telophase.
So, the correct answer is option A.
