B. `alpha`-Carotene
C. Fucoxanthin
D. Anthocyanin.

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to Chlamydomonas, which is a unicellular eukaryote belonging to the kingdom Protista.

2. **Understand the Structures**: The question specifically mentions hypnospores and zygospores. Zygospores are formed during sexual reproduction in Chlamydomonas.

3. **Determine the Pigment**: The options provided are hematochrome, alpha keratin, fucoxanthin, and anthocyanin. We need to identify which pigment is present in the zygospores of Chlamydomonas.

4. **Analyze the Options**:
- **Hematochrome**: This pigment is known to be present in the zygospores of Chlamydomonas.
- **Alpha Keratin**: This is a type of protein found in hair and nails, not a pigment.
- **Fucoxanthin**: This pigment is found in brown algae, not in Chlamydomonas.
- **Anthocyanin**: This pigment is present in various plants, particularly in fruits and flowers, but not specifically in Chlamydomonas zygospores.

5. **Select the Correct Answer**: Based on the analysis, the pigment present in the zygospores of Chlamydomonas is hematochrome.

**Final Answer**: Hematochrome
