Options

A. Brassicaceae
B. Solanaceae
C. Fabaceae
D. Liliaceae

Answer

**Step-by-Step Solution:**

1. **Understanding Tetradynamous Stamens**: Tetradynamous stamens are defined as a condition where there are six stamens in total, with four being longer and two being shorter. This unique arrangement is a key characteristic of certain flowering plants.

2. **Identifying the Family**: The question asks which family exhibits tetradynamous stamens. The family that is well-known for this characteristic is the Brassicaceae family, commonly referred to as the cabbage family.

3. **Analyzing Other Families**: To confirm that Brassicaceae is the correct answer, we can look at other families:
- **Solanaceae**: This family typically has three stamens.
- **Fabaceae**: In this family, the stamens are usually arranged as three plus three, totaling six but not in the tetradynamous arrangement.
- **Liliaceae**: This family generally has five stamens.

4. **Conclusion**: Since the Brassicaceae family is the only one that possesses the tetradynamous arrangement of stamens (4 long and 2 short), it is the correct answer to the question.

**Final Answer**: Tetradynamous stamens are characteristic of the Brassicaceae family.
