Explanation

To solve the question regarding the family to which the tetradynamous type of stamens are found, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Tetradynamous":**
- The term "tetradynamous" refers to a specific arrangement of stamens in a flower where there are four long stamens and two short stamens. This results in a total of six stamens.

2. **Identify the Characteristics of Tetradynamous Stamens:**

4. **Eliminate Other Options:**
- The question provides multiple options. We need to eliminate the incorrect families:
- **Malvaceae**: This family does not exhibit tetradynamous stamens.
- **Solanaceae** (potato family): This family also does not have this characteristic.
- **Liliaceae** (lily family): Similarly, this family does not have tetradynamous stamens.

5. **Conclude the Answer:**
- Based on the characteristics and the elimination of other options, we conclude that the family to which the tetradynamous type of stamens belongs is **Brassicaceae**.

### Final Answer:
The family to which the tetradynamous type of stamens are found is **Brassicaceae**.
