Assertion: Age, sex, structure of human popuJation in France and Sweden forms a steep pyramid.
Reason: To countries like Sudan and Lndia, the population is increasing at a rapid rate.

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the age and sex structure of the human population in France and Sweden forms a steep pyramid.
- In demographic terms, a steep pyramid indicates a population with a high proportion of older individuals, which is characteristic of developed countries with low birth rates and low death rates.

2. **Analyzing the Assertion**:
- France and Sweden are known for their stable populations and low birth rates.
- Their age pyramids typically show a more rectangular shape rather than a steep pyramid, indicating a balanced age distribution with a significant proportion of older adults.
- Therefore, the assertion is **incorrect**.

3. **Understanding the Reason**:
- The reason states that countries like Sudan and India have populations that are increasing at a rapid rate.
- This is true as both countries have higher birth rates compared to developed nations, leading to rapid population growth.

4. **Analyzing the Reason**:
- The population growth rates for Sudan and India are indeed high, with Sudan at approximately 2.60% and India at about 1.40%.
- Thus, the reason is **correct**.

5. **Determining the Relationship**:
- The assertion is incorrect, while the reason is correct.
- The reason does not explain the assertion, as the population structure in France and Sweden does not correlate with the rapid growth in Sudan and India.

### Conclusion:
- The correct answer is that the assertion is false, and the reason is true. Therefore, the final conclusion is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
- **Option B**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
