Biology

The correct answer is: C.Chromosomes are pulled apart to opposite poles.

During anaphase, the sister chromatids are separated and pulled toward opposite poles of the cell. This is facilitated by the shortening of the spindle fibers attached to the centromeres of the chromosomes.

Here's a breakdown of the other options:

A.Chromosomes condense into chromatids: This happens earlier, during prophase when chromatin condenses into visible chromosomes, and the chromatids are already formed by then.
