Answer

Explanation:

Step1: Find range of Set A

Range = Max - Min. For Set A: Max=94, Min=74. So range = ( 94 - 74 = 20 ).

Step2: Find range of Set B

For Set B: Max=94, Min=73. Range = ( 94 - 73 = 21 ).

Step3: Find range of Set C

For Set C: Max=91, Min=73. Range = ( 91 - 73 = 18 ).

Step4: Find range of Set D

For Set D: Max=99, Min=82. Range = ( 99 - 82 = 17 ).

Step5: Compare ranges

Set B has range 21, which is greater than others (20, 18, 17).

B. Set B
