• A. Pituitary gland

• C. Pancreas
• D. Thyroid gland

Answer: (C)

Verified step by step guidance

1. Step 1: Understand the difference between endocrine and exocrine glands. Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands release substances through ducts to an external or internal surface.
2. Step 2: Identify the glands listed and their primary functions. The pituitary gland and thyroid gland are primarily endocrine glands, secreting hormones into the blood.
3. Step 3: Recognize that the adrenal gland is also an endocrine gland, producing hormones like adrenaline and cortisol, but it does not have an exocrine function.
4. Step 4: Recall that the pancreas has a dual role: it acts as an endocrine gland by secreting hormones such as insulin and glucagon into the bloodstream, and as an exocrine gland by producing digestive enzymes that are secreted into the small intestine via ducts.
5. Step 5: Conclude that the pancreas is the gland with both endocrine and exocrine functions, making it unique among the options provided.
