Answer:
The correct answer would be Metaphase.
The metaphase is the second stage of the mitosis during which all the sister chromatids are arranged at the imaginary central line termed as metaphase plate.
The centromere of each chromosome is attached with two microtubules coming from the opposite ends of a cell.
It helps in equal distribution of sister chromatids into two daughter cells.
Once the metaphase passes the cell cycle checkpoint, the cell progress to anaphase.
