Verified step by step guidance

Step 1: Understand the question by identifying the key concept being tested, which is the anatomical differences between children and adults. This involves comparing structural and developmental characteristics.

Step 2: Analyze each option provided in the question. For example, consider the proportional size of the tongue relative to the mouth, the size of the head compared to the body, the number of bones in the hands, and the development of the larynx at birth.

Step 3: Recall relevant anatomical knowledge: (a) Children have proportionally larger heads compared to their bodies than adults due to developmental differences. (b) Children have more bones in their hands because some bones are not yet fused. (c) The larynx is not fully developed at birth; it undergoes changes during growth. (d) The tongue is proportionally larger in children relative to their mouth compared to adults.

Step 4: Eliminate incorrect options based on anatomical facts. For example, the statement about the larynx being fully developed at birth is incorrect, as the larynx continues to develop during childhood. Similarly, the statement about the tongue being smaller relative to the mouth is incorrect.

Step 5: Select the correct answer based on the analysis. The correct anatomical difference is that children have proportionally larger heads compared to their bodies than adults.
