What problem occurs if the chosen reference unit is changed midway during sight measurement?

Answer and explanation

Correct answer: The scale of measurements will become inconsistent

Sight measurement depends on comparing every dimension with one fixed reference, such as the width of a particular object. If that unit is changed halfway through, widths, heights, distances and angles are no longer based on the same scale, so proportional relationships become unreliable. Option C is correct. Changing the unit does not automatically sharpen objects, increase tonal contrast or alter the physical length of a cast shadow.
