Answer: Human females.
- A Human males
- B Human females
- C Bacteria
- D All flowering plants
Correct answer: B. Human females
Explanation: In human females, primary oocytes are arrested at the diplotene stage of meiosis I for years, resuming only around ovulation.
The cell cycle: G1 (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G2 (final checks before division), and M (mitosis itself) - together, G1+S+G2 make up interphase.
