D. One-fourth

Answer

**Step-by-Step Solution:**

1. **Understanding Proportions at Birth:**
- At birth, the proportions of a newborn's body are different from those of an adult. The head is relatively larger compared to the rest of the body.

2. **Head Circumference:**
- The normal head circumference for a full-term newborn is approximately 33 to 36 centimeters. This indicates that the head is quite large in proportion to the body.

3. **Cranium and Fontanelles:**
- The cranium of a newborn is not fully fused; it contains soft regions known as fontanelles. These allow for growth and flexibility during childbirth.

4. **Proportion of Head to Body Length:**
- It is generally observed that the head of a newborn baby is about 1/4th of the total body length. This is a significant proportion compared to adults, where the head is about 1/8th of the total body length.

5. **Conclusion:**
- Therefore, as compared to the whole body, the head of a newborn human baby is approximately 1/4th of the total body length.

**Final Answer:**
The head of a newborn human body is approximately 1/4th of the total body length.
