If A = {2, 4, 6} and B = {x : x is a positive even number less than 8}, which statement is correct?
Answer and explanation
Correct answer: A = B
The positive even numbers less than 8 are 2, 4, and 6. Thus the condition defining B produces B = {2, 4, 6}, which contains exactly the same elements as A. Two sets are equal when they have precisely the same elements, regardless of how they are written. Therefore A = B and option A is correct.
