Options

A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
B. If both Assertion and Reason are true and the 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 analyze the given assertion and reason, we will break down the statements and evaluate their validity step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "In India, the human population is currently undergoing the lag phase."
- The lag phase in population growth is characterized by slow growth, where the population is just beginning to increase due to limited resources or other factors.

2. **Understanding the Reason**:
- The reason provided is that "A major portion of the Indian population is still below the poverty line."
- This statement highlights the socio-economic condition of a significant part of the population, which can affect growth rates.

3. **Evaluating the Assertion**:
- Currently, the human population in India is not in the lag phase; it is experiencing rapid growth, which is more aligned with the exponential phase of population growth.
- Therefore, the assertion is **false**.

4. **Evaluating the Reason**:
- The reason states that a major portion of the population is below the poverty line, which is a true statement.
- However, this socio-economic condition does not directly correlate with the assertion about the population being in the lag phase.

5. **Conclusion**:
- The assertion is false, while the reason is true.
- Since the reason does not support the assertion, they are not related in a cause-and-effect manner.

### Final Answer:
- **Assertion**: False
- **Reason**: True
- The correct relationship is that the assertion is false, and the reason is true, but they are not linked.
