In mathematics, a SET is defined as:
AA well-defined collection of objects
BA list of numbers in ascending order
CAny group of similar items chosen by personal taste
DAny collection of objects, including subjective ones
Answer & Solution
Correct answer: A. A well-defined collection of objects
A set is a WELL-DEFINED collection — given any object, we can decide unambiguously whether it belongs to the set. 'Five most renowned mathematicians' is NOT a set because 'renowned' is subjective.
