A. Thyroid
B. Liver
C. Pituitary
D. Thymus

Answer

**Step-by-Step Solution:**

1. **Understanding Endocrine Glands**: Endocrine glands are specialized glands that do not have ducts. Instead, they release hormones directly into the bloodstream. These hormones are then transported to various target organs in the body.

2. **Identifying the Options**: The question provides four options: Thyroid, Liver, Pituitary, and Thymus. We need to determine which of these is the largest endocrine gland.

3. **Analyzing Each Option**:
- **Thyroid Gland**: Located in the neck region, it is known for producing hormones such as T3 (triiodothyronine) and T4 (thyroxine), which regulate the body's metabolic rate.
- **Liver**: While it has endocrine functions, it is primarily known as an exocrine gland and is not classified as the largest endocrine gland.
- **Pituitary Gland**: Often referred to as the "master gland" because it regulates other endocrine glands, but it is smaller than the thyroid.
- **Thymus**: This gland is involved in immune function and hormone production, but it is also smaller than the thyroid.

4. **Conclusion**: After analyzing the options, it is clear that the **Thyroid Gland** is the largest endocrine gland in the human body.

5. **Final Answer**: The largest endocrine gland is the **Thyroid Gland**.
