Which option correctly describes Q={2,4,6,8}?
Answer and explanation
Correct answer: Positive even numbers less than 10
A correct description must include every member of Q and exclude every number outside Q. The numbers 2, 4, 6, and 8 are all positive, even, and less than 10, so option A describes exactly this set. Odd numbers below 10 are 1,3,5,7; factors of 10 are 1,2,5,10; and 4,6,8 are not all prime. Thus A is unambiguous.
