The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks which gland is large at birth but reduces significantly in size during adulthood. 2. **Identifying the Options**: The options provided are: - A) Thyroid - B) Adrenal - C) Thymus - D) Spleen 3. **Analyzing Each Option**: - **Thyroid Gland**: This gland is responsible for metabolism regulation and does not significantly change in size from birth to adulthood. - **Adrenal Gland**: This gland produces hormones like adrenaline and cortisol, and its size remains relatively constant throughout life. - **Thymus Gland**: This gland is crucial for the immune system, particularly in the maturation of T-cells. It is large at birth and decreases in size after puberty. - **Spleen**: The spleen plays a role in filtering blood and immune response, and its size does not significantly change from birth to adulthood. 4. **Conclusion**: After analyzing the options, the thymus gland is the only gland that is large at birth and reduces to a small size in adults. Therefore, the correct answer is **C) Thymus**. ---
