Question
**The figure below represents the relative amount of nuclear DNA during different segments of consecutive cell cycles.**

![Graph showing DNA amount during cell cycles](#)

In the graph, the x-axis represents the cell cycle stages, indicated as "cycle I" and "cycle II." The y-axis represents the "amount of DNA in nucleus."

The graph is divided into five numbered regions:

- **Region I:** Shows a constant DNA amount at the start of cycle I.
- **Region II:** Demonstrates an increase in DNA amount, indicating DNA replication.
- **Region III:** DNA amount remains constant post-replication.
- **Region IV:** Shows a sharp decrease in DNA amount.
- **Region V:** DNA amount remains low, similar to Region I.

**Amount of nuclear DNA in an actively dividing cell.**

**According to the figure above, which of the numbered regions represents the S phase?**

- A I ⬜
- B II ⬜
- C III ⬜
- D IV ⬜
