Answer: Haploid (n).
- A Tetraploid (4n)
- B Diploid (2n)
- C Haploid (n)
- D Triploid (3n)
Correct answer: C. Haploid (n)
Explanation: After Meiosis I, cells are haploid (n) but with sister chromatids still joined. Meiosis II separates the chromatids.
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.
