Head of the newly born baby is _____ of the total length of the body.

Question

Accepted Answer

The correct answer to the question "Head of the newly born baby is _____ of the total length of the body" is Option 2: one fourth. Here is a detailed explanation supporting this answer:

1. **Explanation for Option 2 (one fourth):**
   - In newborns, the head is proportionally larger compared to the rest of the body than in adults. This is because the head contains the brain, which is relatively well-developed at birth compared to other parts of the body. On average, the head of a newborn baby accounts for about one fourth of the total body length. This proportion reflects the significant size of the head relative to the rest of the body during early development.

2. **Why Option 1 (one tenth) is incorrect:**
   - If the head were only one tenth of the total body length, it would imply that the head is much smaller in proportion to the body than it actually is in newborns. This proportion is more typical of older children or adults, where the body grows more significantly compared to the head.

3. **Why Option 3 (one fifth) is incorrect:**
   - While one fifth is closer to the correct proportion than one tenth, it still underestimates the size of the head relative to the body in newborns. The head is larger than one fifth of the total body length at birth, making this option inaccurate.

4. **Why Option 4 (one third) is incorrect:**
   - One third overestimates the size of the head in relation to the body. While the head is large, it does not constitute one third of the total body length. This proportion would suggest an even larger head than is typical for newborns.

In conclusion, Option 2 is the correct answer because it accurately reflects the proportion of the head to the total body length in newborns, which is approximately one fourth. This proportion is consistent with the developmental characteristics of infants, where the head is notably large compared to the rest of the body.
