Correct answer and explanation

Correct answer: Jiffy

Explanation: āœ… Correct Answer: D. Jiffy šŸ“š Explanation: Light year, Parsec, and Furlong are all units used to measure 'distance' in various contexts (astronomy and traditional land measurement). A 'Jiffy' is an informal term for an extremely short period of 'time'. In physics, a jiffy is specifically the time it takes for light to travel one centimeter in a vacuum. Therefore, it is the only term in the list that refers to time rather than length.
