Which collection is most suitable to be called a set?
Answer and explanation
Correct answer: A list of 40 students in a class
The governing concept is that a set must be well-defined: membership should be decidable without personal opinion. A list of 40 students identifies a definite collection, so every member can be recognized objectively. The terms beautiful, good, and tall may be judged differently by different people unless a precise standard is supplied. Thus only the collection in option A is clearly a set.
