When LAT equals LMT, which is true?

Explanation:
The question tests understanding of what the equation of time represents. Local Apparent Time (LAT) is based on the Sun’s actual position in the sky, while Local Mean Time (LMT) is based on the average or mean Sun’s position. The equation of time is the difference between these two ways of reading time. When LAT equals LMT, there is no difference between the Sun’s true position and the mean Sun’s position, so the equation of time is zero. This occurs on specific days each year when the Sun’s apparent motion aligns with the mean solar motion. The other options imply a nonzero or large offset, which isn’t the case when LAT and LMT coincide.
