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):**
   - At birth, a baby's head is proportionally larger compared to the rest of its body than at any other stage of life. The head of a newborn typically accounts for about one-fourth (25%) of the total body length. This is because the brain and skull develop rapidly during fetal development, resulting in a relatively large head size at birth. This proportion is a well-documented fact in pediatric and developmental studies, reflecting the significant growth and development of the brain during the prenatal period.

2. **Why Option 1 (One Tenth) is Incorrect:**
   - One tenth would imply that the head is only 10% of the total body length, which is not accurate for newborns. This proportion is more characteristic of older children or adults, where the head becomes a smaller fraction of the total body length as the rest of the body grows.

3. **Why Option 3 (One Fifth) is Incorrect:**
   - While one fifth (20%) might seem closer to the correct proportion, it still underestimates the size of a newborn's head relative to its body. The head is larger than one fifth of the total body length at birth, making this option incorrect.

4. **Why Option 4 (One Third) is Incorrect:**
   - One third would suggest that the head is 33% of the total body length, which overestimates the size of the head in relation to the body. This proportion is too large and does not accurately reflect the typical measurements of a newborn.

In conclusion, Option 2 (One Fourth) is the correct answer because it accurately represents the proportion of a newborn's head to its total body length, based on established medical and developmental knowledge.
