Metaphase is a stage in the process of cell division (mitosis or meiosis). Normally, chromosomes are scattered throughout the nucleus of the cell.
Thus, Option B is correct.
What causes metaphase to occur?
Metaphase. At the metaphase plate, the mitotic spindle draws the chromosomes together. Microtubules from opposite spindle poles grip each chromosome's two sister chromatids.
During metaphase, the spindle has gathered all of the chromosomes and lined them up in the center of the cell, ready to divide.
