What is the best definition for the word "protracted"?

The term "protracted" is best defined as "extended." It is often used to describe something that is prolonged in duration or stretched out over a period of time. This could refer to a situation, a negotiation, or a condition that takes longer than initially expected or desired. When something is protracted, it suggests that it has been lengthened or dragged out, which aligns closely with the definition of "extended."

The other choices—"required," "elevated," and "delayed"—do not capture the essence of the term as accurately. While "delayed" could imply something taking longer than anticipated, it does not necessarily convey the same sense of duration as "extended." Therefore, "extended" is the most fitting definition for "protracted."
