B. Scattered , conjoint and closed vascular bundle
C. Both a and b
D. None of these

Answer

To solve the question regarding the characteristics of a monocotyledonous stem, we can break down the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Monocotyledonous Stem**:
- Monocotyledonous plants (monocots) are characterized by having one cotyledon in their seeds. Common examples include grasses, lilies, and palms.

2. **Identifying the Features**:
- The question asks about the features present in a monocotyledonous stem. We need to analyze the options provided.

3. **Option Analysis**:
- **Option A: Sclerenchymatous Hypodermis**:
- The hypodermis in monocot stems is typically composed of sclerenchyma, which provides structural support. It is usually 2 to 3 layers thick and lies beneath the epidermis.
- This option is correct.

- **Option B: Scattered, Conjoined, and Closed Vascular Bundles**:
- In monocot stems, vascular bundles are indeed scattered throughout the stem and are typically conjoined and closed. This means that the xylem and phloem are found together in the same bundle and do not form a continuous ring as seen in dicots.
- This option is also correct.

4. **Combining Options**:
- **Option C: Both A and B**:
- Since both Option A and Option B are correct, this option is also correct.

- **Option D: None of these**:
- This option is incorrect as we have established that both A and B are correct.

5. **Final Answer**:
- The correct answer is **Option C: Both A and B**.
