Show answer and explanation

Correct answer: (A) Checks maximum material condition and as many dimensions as possible.

Explanation

A GO gauge checks the full form at maximum material condition so mating features will assemble. The NO-GO gauge checks individual size limits at the other extreme. Thus A correctly combines maximum material with the full-form or multidimension requirement.
