Which term means already existing?

• A. Preexisting
• B. Primary
• C. Priority
• D. Prognosis

Answer: (A)

The idea is about indicating existence before a certain time. A term built to mean existing prior to something is preexisting. That fits the clue because it conveys that something already exists before a given point.

Primary means first or most important, not about when something exists. Priority refers to what should be addressed first or is of higher urgency. Prognosis is a forecast of how a disease will progress. None of those describe existence in the past the way preexisting does.
