B. false; adult humans have 206 bones.
The statement that humans have 221 bones is False. Human adults have 206 bones. At birth, humans have approximately 270 bones, which fuse together during growth to form the final count of 206 bones in adulthood. The bones in the human skeleton are categorized into two main parts: the axial skeleton (which includes the vertebral column, ribs, sternum, and skull) and the appendicular skeleton (which includes the bones of the limbs and girdles).
