D. Testes -placenta

Answer

To answer the question "Both organs of which set secretes hormones?", we need to analyze the given options and identify the organs that are known for hormone secretion.

### Step-by-Step Solution:

1. **Identify the Organs in Each Option**:
- We need to look at the organs listed in each option. The question implies that we are looking for a set of two organs that both secrete hormones.

2. **Evaluate Each Option**:
- **Option 1**: Contains the spleen. The spleen primarily functions in filtering blood and does not secrete hormones. Therefore, this option is incorrect.
- **Option 2**: Again contains the spleen. As established, the spleen does not secrete hormones, making this option incorrect as well.
- **Option 3**: This option is not specified in the transcript, but we can assume it might also contain organs that do not secrete hormones based on the previous options.
- **Option 4**: Contains the testis and placenta. The testis is known for secreting androgens, particularly testosterone. The placenta also secretes hormones such as human chorionic gonadotropin (hCG) and human placental lactogen (HPL).

3. **Conclusion**:
- Since both the testis and placenta are known to secrete hormones, the correct answer is **Option 4**.

### Final Answer:
The correct option is **4th**, which includes the testis and placenta, both of which secrete hormones.
