Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the 'soft spots' in the skull of a newborn infant.

2. **Identifying the Skull Structure**: The skull of a newborn is made up of six cranial bones:
- Frontal bone
- Occipital bone
- Two parietal bones
- Two temporal bones

3. **Connection Between Bones**: These cranial bones are not fused together in newborns. Instead, they are held together by strong fibrous elastic tissue.

4. **Identifying Soft Spots**: The areas where these bones meet and are not fused are referred to as 'soft spots'. These specific areas are known as fontanels.

5. **Function of Fontanels**: The fontanels remain open to allow for the normal development of the infant's brain and skull. This flexibility is crucial during childbirth and for the growth of the brain.

6. **Conclusion**: The correct answer to the question is option B, which states that the soft spots in the skull of a newborn infant are known as fontanels.
