D. Three

Answer

**Step-by-Step Solution:**

1. **Understanding Plant Categories**:
- There are three main categories of plants based on their life cycles: annual, biennial, and perennial.
- Annual plants complete their life cycle in one year, biennial plants in two years, and perennial plants can live for many years.

2. **Focusing on Biennial Plants**:
- Biennial plants, as indicated by the prefix "bi," have a life cycle that spans two years.
- In the first year, these plants grow leaves, stems, and roots. They prepare for the next phase of their life cycle.

3. **Flowering in Biennial Plants**:
- After the first year, during the second year, biennial plants flower. This typically occurs in the spring after a period of dormancy during winter.
- After flowering, they produce seeds and then die.

4. **Conclusion**:
- Since biennial plants only flower in their second year of life, they flower only once during their life cycle.

**Final Answer**: Biennial plants flower **once**.
