How can G = {2, 3, 5, 7} be described most accurately?
Answer and explanation
Correct answer: Prime natural numbers less than 10
A set-builder description must include every listed element and exclude numbers not in the set. The numbers 2, 3, 5, and 7 are all prime natural numbers less than 10, so option A is exact. Option B would contain only 2, 4, 6, and 8. Option C is too broad because it also includes 1 and 9, while option D gives 1, 4, and 9.
