The major excretory product in human beings is

Options

A. uric acid
B. ammonium chloride
C. urea
D. ammonia

Explanation

To determine the major excretory product in human beings, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Excretory System**: The human excretory system consists of the kidneys, ureters, urinary bladder, and urethra. This system is responsible for the removal of waste products from the body.

2. **Identify Metabolic Waste Products**: Metabolic waste products are substances produced during metabolism that need to be excreted from the body. Common metabolic waste products include urea, uric acid, ammonia, and ammonium chloride.

3. **Determine the Major Excretory Product**: Among the waste products mentioned, we need to identify which one is primarily excreted by humans.

4. **Analyze Each Option**:
- **Option A: Uric Acid**: This is primarily excreted by birds and reptiles.
- **Option B: Ammonium Chloride**: This is not a major excretory product in humans.
- **Option C: Urea**: This is the primary nitrogenous waste product excreted by humans.
- **Option D: Ammonia**: While ammonia is a waste product, it is highly toxic and is converted to urea in the liver for safer excretion.

5. **Conclusion**: Based on the analysis, the major excretory product in humans is **urea**.

### Final Answer:
The major excretory product in human beings is **urea** (Option C).
