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 is defined as the average number of children that would be born to a woman over her lifetime.

2. **Confirming the Assertion:**
- It is a well-documented fact that U.P. and Bihar have some of the highest TFRs in India.
- This can be attributed to various socio-economic factors, including limited access to education and family planning services.

3. **Understanding the Reason:**
- The reason given is that polygamy is very common in these states.
- Polygamy refers to the practice of marrying multiple spouses, which can lead to higher fertility rates since one man can have children with multiple women.

4. **Evaluating the Reason:**
- In U.P. and Bihar, while polygamy may not be the predominant practice, it does exist and can contribute to higher fertility rates.
- The presence of polygamy can indeed increase the average number of children born per man, thus impacting the overall TFR.

5. **Conclusion:**
- Both the assertion and the reason are correct.
- The reason provided does explain the assertion, as polygamy can lead to higher fertility rates, contributing to the high TFR in these states.

6. **Final Answer:**
- The correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.
