Malfunctioning of ________ gland in the human body could affect the proper working of all other glands.

Options

A. Pituitary
B. Adrenal
C. Thyroid
D. Pancreas

Answer

To solve the question "Malfunctioning of ________ gland in the human body could affect the proper working of all other glands," we need to identify which gland is referred to as the "master gland" that regulates the functions of other glands in the endocrine system.

### Step-by-Step Solution:

1. **Identify the Glands**: The question mentions several glands: Pituitary, Adrenal, Thyroid, and Pancreas. We need to analyze each of these glands to determine which one has the most significant impact on the functioning of other glands.

2. **Understand the Role of Each Gland**:
- **Pituitary Gland**: Known as the "master gland," it produces hormones that regulate various bodily functions and control other endocrine glands.
- **Adrenal Gland**: Produces hormones that help regulate metabolism, immune response, and stress.
- **Thyroid Gland**: Plays a crucial role in metabolism, growth, and development.
- **Pancreas**: Has both exocrine functions (related to digestion) and endocrine functions (regulating blood sugar levels).

3. **Analyze the Impact of Malfunction**:
- If the **Pituitary Gland** malfunctions, it can lead to a cascade of issues affecting other glands, as it controls their activity.
- Malfunctioning of the **Adrenal**, **Thyroid**, or **Pancreas** would primarily affect their specific functions but would not directly impact the functioning of all other glands.

4. **Conclusion**: Based on the analysis, the gland whose malfunctioning could affect the proper working of all other glands is the **Pituitary Gland**.

### Final Answer:
Malfunctioning of **Pituitary** gland in the human body could affect the proper working of all other glands.
