### Step-by-Step Solution:

1. **Understand the Term 'Deuteromycetes':**
- Deuteromycetes, also known as Fungi imperfecti, are a group of fungi that do not have a known sexual reproductive stage.

- This option is also incorrect because Deuteromycetes do possess true mycelium, which is a network of hyphae.
- **Option C: Sexual Cycle**
- This option is correct. Deuteromycetes are called Fungi imperfecti because they lack a sexual reproductive cycle.
- **Option D: Septate Hyphae**
- This option is incorrect as well, since many Deuteromycetes have septate hyphae.

4. **Conclusion:**
