"Radiate" has quite a few meanings, and three of the following sentences correctly show different meanings of "radiate" in use. Which one of the sentences below uses "radiate" in a way that does NOT make sense?

A plant's roots soak up water, rather than radiate it, so Sentence C does not make sense. The other sentences all show "radiate" being used correctly in one of the ways the word is defined. "Radiate" comes from the Latin word "radius," meaning "ray." "Radius" also gave us the English word "radius." Among the several meanings of English "radius" is one you may come across in math class: "a line extending from the center of a circle or sphere to the circumference or surface." The familiar words "radio" and "ray" (as in "ray of light") also come from "radius."
