Which combining form means x-rays?

Explanation:
Combining forms are roots paired with a vowel that let you build medical terms. The one that means X‑rays is radi/o, which appears in words like radiology, radiograph, and radiologist—all centered on imaging with X‑rays. The other options map to different concepts: ren/o relates to the kidney, rhin/o to the nose, and pyo- means pus. So radi/o is the correct combining form for X‑rays.
