Assertion: In maize stem, endodermis is present between general cortex and pericycle.
Reason: Eustele is present in maize Stem.

Options

A. If both Assertion & Reason are true and the reason is the correct expalanation of the assertion. Then mark (1).
B. If Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the assertion and reason question regarding maize stem, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "In maize stem, endodermis is present between general cortex and pericycle."
- In the anatomy of maize (a monocot), the structure of the stem includes layers such as the epidermis, cortex, and vascular bundles. The endodermis is typically a single layer of cells that surrounds the vascular tissue in roots but in stems, especially in monocots like maize, the endodermis is not present in the same way as in dicots.

2. **Evaluating the Assertion**:
- In maize stems, the general cortex is present, but the endodermis does not exist between the general cortex and pericycle. Instead, the pericycle is located just inside the endodermis in roots, but in stems, the arrangement is different.
- Therefore, the assertion is **false**.

3. **Understanding the Reason**:
- The reason states that "Eustele is present in maize stem."
- Eustele refers to a type of vascular arrangement where vascular bundles are arranged in a ring, which is typical of dicots. In contrast, maize, being a monocot, has scattered vascular bundles, which is characteristic of aatactostele.

4. **Evaluating the Reason**:
- Since maize has scattered vascular bundles, it does not exhibit eustele. Thus, the reason is also **false**.

5. **Conclusion**:
- Both the assertion and the reason are false. Therefore, the correct answer is that both the assertion and reason are false.

### Final Answer:
Both the assertion and the reason are false.
