Assertion and reason type questions (for AIIMS aspirants)
Assertion: U.P. and Bihar have high TFR.
Reason: Polygamy is very common in these states.

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.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that Uttar Pradesh (U.P.) and Bihar have a high Total Fertility Rate (TFR). TFR refers to the average number of children that would be born to a woman over her lifetime.
- In this context, both U.P. and Bihar are known for having higher population growth rates compared to other states in India, which supports the assertion as true.

2. **Understanding the Reason**:
- The reason provided is that polygamy is very common in these states. Polygamy refers to the practice of having more than one spouse at the same time.
- While polygamy does exist in certain communities within these states, it is not the sole factor influencing the high TFR.

3. **Evaluating the Relationship**:
- Both the assertion and reason are true statements. However, the reason does not adequately explain why U.P. and Bihar have a high TFR.
- High fertility rates can be attributed to various factors such as socio-economic conditions, education levels, access to healthcare, and cultural norms, not just polygamy.

4. **Conclusion**:
- Since both statements are true but the reason does not correctly explain the assertion, the correct answer is that the assertion is true, and the reason is also true, but it is not the correct explanation of the assertion.

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