The correct answer is option 'D' - None of these. None of the given options - Thyroid, Pituitary, or Adrenal glands - have both exocrine and endocrine parts.

Let's discuss the functions and characteristics of each of these glands to understand why none of them fits the description:

1. Thyroid Gland:
The thyroid gland is located in the neck and is responsible for producing hormones that regulate metabolism and growth. It only has endocrine functions and does not possess any exocrine functions.

2. Pituitary Gland:
The pituitary gland, also known as the "master gland," is located at the base of the brain. It controls the functions of other endocrine glands by producing and releasing various hormones. The pituitary gland is purely an endocrine gland and does not have any exocrine functions.

3. Adrenal Gland:
The adrenal glands are located on top of each kidney. They have two main parts - the adrenal cortex and the adrenal medulla. The adrenal cortex secretes hormones such as cortisol and aldosterone, which are involved in regulating metabolism and electrolyte balance. The adrenal medulla secretes adrenaline and noradrenaline, which are involved in the body's stress response. While the adrenal gland has endocrine functions, it does not have any exocrine functions.

Therefore, none of the given options have both exocrine and endocrine parts. It is important to note that exocrine glands secrete substances through ducts, such as sweat glands and salivary glands, while endocrine glands secrete hormones directly into the bloodstream.
