Options

A. thyroid
B. pituitary
C. adrenal
D. pancreas

Answer

**Step-by-Step Solution:**

1. **Understanding Endocrine Glands**: Endocrine glands are ductless glands that secrete hormones directly into the bloodstream. These hormones regulate various bodily functions, including growth, metabolism, and mood.

2. **Identifying the Glands**: The question provides four options: thyroid, pituitary, adrenal, and pancreas. We need to determine which of these glands is responsible for height regulation.

3. **Role of the Pituitary Gland**: The pituitary gland is often referred to as the "master gland" because it controls other endocrine glands and regulates important functions in the body, including growth.

4. **Growth Hormone (GH)**: The pituitary gland produces a hormone known as Growth Hormone (GH), which is crucial for growth and development. If the pituitary gland does not function properly, it can lead to growth disorders, resulting in a person being very short (dwarfism) or very tall (gigantism).

5. **Conclusion**: Based on the information, the gland responsible for height regulation is the pituitary gland.

**Final Answer**: The faulty functioning of an endocrine gland that can make a person very short or very tall is the **pituitary gland**.
