Correct answer and explanation

Correct answer: None of the above

Explanation: āœ… Correct Answer: D. None of the above šŸ“š Explanation: In humans, an ovum (egg cell) is a gamete, which means it is a haploid cell containing only half the total number of chromosomes. The correct number of chromosomes in a human ovum is 23. Since 23 is not listed in the options, 'None of the above' is the correct choice. When the ovum is fertilized by a sperm (also 23), the resulting zygote has the full 46 chromosomes.
