Which spanner from the options will fit the maximum number of nuts shown on the left?
Show Hint
Do not just look at the absolute largest or smallest sizes. In design exams, distribution-matching questions always reward the option that targets the average and slightly above-average size ranges, as they have the highest frequency.
Step 1: Compare jaw openings. Visually gauge each spanner's jaw width against the range of hexagonal nut sizes shown. Step 2: Count matches. Tally how many nuts each spanner can grip; Spanner C spans the widest set of nut sizes. \[ \boxed{\text{Option 3 (Fig C)}} \]
