C. Bipinnate
D. Trifoliate

Answer

### Step-by-Step Solution

1. **Understand the Question**: The question asks about the type of leaf structure found in Mimosa pudica, commonly known as the touch-me-not plant.

2. **Identify the Options**: The options provided are:
- Simple
- Bifoliate
- Bipinnate
- Trifoliate

3. **Define Each Leaf Type**:
- **Simple Leaf**: A leaf that consists of a single, undivided blade without any leaflets.
- **Bifoliate Leaf**: A leaf that has exactly two leaflets.
- **Trifoliate Leaf**: A leaf that has three leaflets.
- **Bipinnate Leaf**: A compound leaf with multiple leaflets arranged along a central rachis.

4. **Analyze Mimosa pudica**:
- Upon examining the structure of the leaves of Mimosa pudica, it is evident that the leaves are not simple, as they consist of multiple leaflets.
- The presence of more than two leaflets rules out the bifoliate option.
- The presence of more than three leaflets rules out the trifoliate option.

5. **Determine the Correct Option**:
- Since the leaves of Mimosa pudica consist of many leaflets arranged along a central rachis, they fit the definition of a bipinnate leaf. This means that the leaf structure is compound and has a bipinnate arrangement.

6. **Final Answer**: The leaf of Mimosa pudica is **bipinnate**.
