Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that hCG (human chorionic gonadotropin), hPL (human placental lactogen), and relaxin are produced in women only during pregnancy.
- hCG is a hormone that is crucial for maintaining pregnancy and is often used in pregnancy tests.

2. **Understanding the Reason:**
- The reason given is that these hormones are produced by the placenta.
- It is important to analyze whether this statement is true for all three hormones mentioned.

3. **Analyzing hCG:**
- hCG is indeed produced by the placenta during pregnancy. It helps in maintaining the corpus luteum and supports the early stages of pregnancy.

4. **Analyzing hPL:**
- hPL is also produced by the placenta. It plays a role in metabolic adjustments during pregnancy and helps in fetal development.

5. **Analyzing Relaxin:**
- Relaxin is a hormone that helps in relaxing the uterine ligaments and is primarily produced by the ovaries during pregnancy, particularly in the later stages, rather than by the placenta.

6. **Conclusion:**
- The assertion is true as hCG and hPL are produced during pregnancy, but the reason is false because relaxin is not produced by the placenta but by the ovaries.
- Therefore, the correct answer is that the assertion is true, but the reason is false.

**Final Answer:**
- Assertion is true, Reason is false. (Option 3)
