Which collection can be considered a mathematical set?
Answer and explanation
Correct answer: Even numbers less than 10
A mathematical set must be well-defined, meaning that membership can be decided objectively and consistently. The even natural numbers less than 10 are exactly 2, 4, 6, and 8, so there is no ambiguity. In contrast, good, beautiful, and interesting depend on personal opinion. Therefore option C describes a set.
