B. The cell cannot be a human
Explanation:
Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome. A mutation would not cause there to be 64. So, A cannot be true. Prokaryotic cells usually have one chromosome, not 64, so C cannot be true.
