The correct answer is: B.Metaphase

During metaphase, the chromosomes align along the metaphase plate in the center of the cell. This alignment is essential for ensuring that each daughter cell will receive an identical set of chromosomes when they are separated in the next stage, anaphase.

Here's why the other stages are incorrect:

A.Prophase: Chromosomes condense, and the nuclear envelope begins to break down, but the chromosomes are not yet aligned.
