Out of the given lines pers millimeter (lp/mm) selections for spatial frequency, which would represent the highest Modulation Transfer Functions (MTF) score?

Explanation:
MTF shows how well image contrast is preserved as detail increases. Spatial frequency, measured in lines per millimeter, indicates how fine the pattern is: more lines per millimeter means finer detail. An imaging system generally transfers coarse patterns with higher fidelity than fine ones, so the MTF decreases as spatial frequency increases. Therefore, the highest MTF score occurs at the smallest spatial frequency among the options. The option representing the lowest frequency will have the highest MTF, while the others with higher frequencies will have lower MTF values.
