Which root denotes bone?

Which root denotes bone?

• A. Rhin
• B. Stoma
• C. Osteo
• D. Angio

Answer: (C)

Osteo- denotes bone. In medical terms, this combining form appears in words like osteoarthritis, osteoblast, and osteogenesis, all referring to bone. The other roots correspond to different parts: rhin- means nose (rhinoplasty), stoma- means mouth or an opening (stomatitis), and angio- means vessels (angiography). Because the question asks for the root that denotes bone, osteo- is the correct choice.
