Assertion. In basal placentation many ovules are present.
Reason. It is bilocular.

Options

A. If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is true but the Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason about basal placentation, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "In basal placentation many ovules are present."
- In basal placentation, the ovules are attached at the base of the ovary. However, it is important to note that typically, basal placentation is characterized by having a single locule (unilocular) with a limited number of ovules.

2. **Understanding the Reason**:
- The reason states that "It is bilocular."
- Bilocular means having two locules. In contrast, basal placentation is usually unilocular, meaning it has only one chamber or locule.

3. **Evaluating the Truth of the Statements**:
- The assertion is **false** because basal placentation does not typically have many ovules; it usually has a few or just one.
- The reason is also **false** because basal placentation is unilocular, not bilocular.

4. **Conclusion**:
- Since both the assertion and reason are false, the correct answer to the question is that both statements are incorrect.

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