Which combining form indicates relationship to nature?

• A. Proxim/o
• B. Physic/o
• C. Noct/i
• D. Rhin/o

Answer: (B)

Understanding that a combining form can convey “nature” hinges on the root physis, meaning nature or growth. A combining form derived from this root points to natural properties or functions. The form in question comes from physis, tying it to nature, and it appears in terms like physiology and physiologic, which describe the body’s natural functions and processes. The other roots refer to proximity (near), time (night), and a body part (nose), so they don’t carry the sense of nature.
