a telophase
b metaphase
c prophase
d anaphase

Explanation:

• Prophase: Chromosomes condense, spindle forms.
• Metaphase: Chromosomes align at cell equator.
• Anaphase: Sister chromatids separate into identical chromosomes, pulled to opposite poles.
• Telophase: New nuclei form around chromosome sets.

The described event matches Anaphase.
