Options

A. One-fifth
B. One-sixth
C. One-seventh
D. One-eighth

Answer

To answer the question "As compared to the whole body, the head of an adult human being is:", we need to analyze the proportions of the head relative to the body size in adults.

### Step-by-Step Solution:

1. **Understanding Proportions in Newborns vs. Adults**:
- In newborns, the head is relatively large compared to the body. It constitutes about one-fourth (1/4) of the total body length.
- As humans grow, the proportion of the head to the body changes significantly.

2. **Adult Human Proportions**:
- In adults, the head becomes smaller in proportion to the body. Research indicates that the head of an adult human is approximately one-seventh (1/7) of the total body length.

3. **Conclusion**:
- Therefore, compared to the whole body, the head of an adult human being is approximately 1/7 of the total body length.

### Final Answer:
The head of an adult human being is approximately **1/7** of the total body length.
