In contrast to adults, children:

• A. Have proportionately larger heads.
• B. Have proportionately smaller heads.
• C. Have larger legs relative to arms.
• D. Have less head-to-body proportion.

Answer: (A)

Children have proportionally larger heads because brain growth drives rapid expansion of the cranium in early life, and the skull bones are not yet fully fused. This makes the head appear oversized relative to the rest of the body, a trait that gives infants and young children a top-heavy look. Over time, the trunk and limbs grow faster, and the body proportions shift toward the smaller head-to-body ratio seen in adults. That’s why the statement that children have proportionately larger heads is the best description. The other ideas don’t fit the typical growth pattern: the head isn’t proportionally smaller, limb proportions aren’t defined by a larger leg relative to the arm in this context, and saying there’s less head-to-body proportion contradicts the observed early-childhood pattern.
