The correct Answer is:
To solve the question regarding the thymus and its secretions, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Organ and Its Function**: The question mentions the thymus, which is a primary lymphoid organ. Its main function is to produce and differentiate a specific type of lymphocyte. 2. **Determine the Type of Lymphocyte**: The thymus is primarily associated with T lymphocytes (also known as T cells). These are crucial for the adaptive immune response. 3. **Identify the Hormone Secreted by the Thymus**: The thymus secretes a hormone that plays a significant role in the differentiation of T lymphocytes. This hormone is known as thymosin. 4. **Classify the Type of Hormone**: Thymosin is classified as a peptide hormone, which is a type of polypeptide. It is not a glycoprotein or steroid hormone. 5. **Match the Information with the Options**: - (a) Glycoproteinaceous, thymosin, T - Incorrect (not glycoproteinaceous) - (b) Steroid, thymosin, T - Incorrect (not steroid) - (c) Peptide, thymosin, T - Correct (thymosin is a peptide hormone and it acts on T lymphocytes) - (d) Peptide, thymosin, B - Incorrect (thymosin acts on T lymphocytes, not B lymphocytes) 6. **Select the Correct Option**: Based on the analysis, the correct answer is option (c) Peptide, thymosin, T. ### Final Answer: The thymus secretes the **peptide** hormone called **thymosin**, which plays a major role in the differentiation of **T** lymphocytes. Therefore, the correct option is (c). ---
