Answer 2

option (B) is correct

Concept:

Range of a set of n values is the difference between greatest and smallest values.

25, 67, 78, 43, 21, 17, 49, 54, 76, 92, 20, 45, 86, 37, 35

Here,

greatest value= 92

smallest value= 17

Range= (Greatest value) - (Smallest value)

Range= 92 - 17

Range= 75
