Which spatial frequency would produce the greatest spatial resolution?

Explanation:
Spatial resolution is the ability to distinguish small, closely spaced details. In imaging, this is quantified by spatial frequency, measured in line pairs per millimeter. A higher spatial frequency means more line pairs fit into each millimeter, which corresponds to finer details and better resolution. Among the options, 6.30 lp/mm is the highest frequency, so it represents the smallest separations that can be resolved and thus the greatest spatial resolution. The lower frequencies—1.12, 3.55, and 4.15 lp/mm—reflect larger features and therefore lower resolution.
