Question

Babies have about 300 bones while adults have only 206. This reduction happens due to -

• A. Disappearance of unwanted bones
• B. Fusion of some bones
• C. Conversion of ligaments to bones
• D. Apoptosis

Answer 1

The correct option is B

Fusion of some bones

The baby skeleton has more bones and cartilages. During development many of these cartilages become bones by the process called ossification and some bones fuse to form a bigger bone reducing the number of bones to 206.
