The Correct Option is D

Solution and Explanation

  • Mitosis Stages: During anaphase, chromosomes are pulled to opposite poles by the spindle fibers.
  • Observation Analysis: The placement of chromosomes at opposite poles indicates anaphase, not metaphase (chromosomes align at the equator), prophase (chromosomes condense), or telophase (nuclear envelopes reform).
  • Conclusion: The correct stage is anaphase.
