The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Gland in Question**: The question asks which gland decreases in size with increasing age. The thymus gland is known for this characteristic. 2. **Location of the Thymus Gland**: The thymus gland is located near the heart and the aorta, which is important for understanding its role in the body. 3. **Function of the Thymus Gland**: The thymus is classified as a primary lymphoid organ. Its primary function is the maturation of T-lymphocytes, which are crucial for the immune system. 4. **Role of T-Lymphocytes**: T-lymphocytes play a vital role in providing immunity. They help the body fight off infections and diseases. 5. **Hormones Secreted by the Thymus**: The thymus gland secretes a hormone called thymosin, which is a peptide hormone that assists in the maturation of T-lymphocytes. 6. **Impact of Aging on the Thymus**: As individuals age, the size of the thymus gland decreases. This reduction leads to decreased production of thymosin, resulting in fewer mature T-lymphocytes. 7. **Consequences of Thymus Size Reduction**: The decrease in T-lymphocytes contributes to weakened immunity in older adults, making them more susceptible to infections and diseases. 8. **Conclusion**: Therefore, the correct answer to the question is the thymus gland, which is option C. ---
