Answer

To determine which is the largest gland in an adult man, we can analyze the options provided:

1. **Thymus**: This gland is primarily involved in the immune system, particularly in the maturation of T-cells. It is not the largest gland in the body.

2. **Liver**: The liver is known to be the largest gland in the human body. It weighs approximately 1.2 to 1.5 kg in adults and is located in the abdominal cavity. The liver plays a crucial role in various metabolic processes, including the secretion of bile, which aids in the digestion of fats.

3. **Thyroid**: The thyroid gland is responsible for regulating metabolism through the production of hormones such as thyroxine. While important, it is not the largest gland.

4. **Pancreas**: The pancreas functions as a mixed gland, producing both hormones (like insulin and glucagon) and digestive enzymes. However, it is smaller than the liver.

After evaluating all the options, we conclude that the largest gland in an adult man is the **liver**.

### Final Answer:
The largest gland in adult man is the **liver**.
