Assertion: A point charge is brought in an electric field. The field at a nearby point will increase, whatever be the nature of the charge.
Reason: The electric field is independent of the nature of charge.

Options

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

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that when a point charge is brought into an electric field, the electric field at a nearby point will increase, regardless of the nature of the charge (positive or negative).
- This implies that the presence of any charge will always lead to an increase in the electric field strength at nearby points.

2. **Understanding the Reason**:
- The reason states that the electric field is independent of the nature of the charge.
- This suggests that the characteristics of the charge (whether it is positive or negative) do not affect the electric field created by the charge itself.

3. **Analyzing the Situation**:
- When a positive charge is placed in an existing electric field, it will create its own electric field that adds to the existing field in some regions and subtracts from it in others.
- Conversely, when a negative charge is placed in the same electric field, it will create an electric field that opposes the existing field.

4. **Conclusion on the Assertion**:
- The assertion is **false**. The electric field at nearby points does not uniformly increase; it can increase in some areas and decrease in others depending on the nature of the charge (positive or negative).

5. **Conclusion on the Reason**:
- The reason is also **false**. The electric field is not independent of the nature of the charge. The nature of the charge (positive or negative) affects how the electric field interacts with the existing field.

6. **Final Evaluation**:
- Since both the assertion and the reason are false, we conclude that the statement provided in the question is incorrect.

### Summary:
- **Assertion**: False
- **Reason**: False
