RADI/O means which of the following?

Explanation:
Radi/o denotes ray or radiation. In medical terminology, this combining form is used for concepts involving X‑rays and other radiant energy, as in radiology (the study of imaging using X‑rays), radiograph (an X‑ray image), and radiation therapy. It isn’t referring to the forearm bone radius, which comes from a different root, nor is it the same as the prefix radio used in terms like radioactivity. So the correct meaning here is Radiation.
