Answer

To determine which of the following is the largest endocrine gland, we need to analyze the options provided:

1. **Pituitary Gland**:
- The pituitary gland is often referred to as the "master gland" because it regulates many bodily functions by releasing hormones that control other glands. However, it is not the largest endocrine gland.

2. **Pancreas**:
- The pancreas has both endocrine and exocrine functions. It plays a crucial role in glucose metabolism by secreting insulin and glucagon. However, it is not considered the largest endocrine gland.

3. **Thyroid Gland**:
- The thyroid gland is located in the neck and is responsible for producing hormones such as thyroxine (T4), triiodothyronine (T3), and calcitonin. It is known for its significant size compared to other endocrine glands and is indeed the largest endocrine gland in the human body.

4. **Testis**:
- The testis is primarily involved in the production of sperm and testosterone. While it is an important endocrine gland, it is not the largest.

Based on this analysis, the answer to the question is:

**The largest endocrine gland is the Thyroid gland.**
