How can U = {0, 2, 4, 6, 8} be correctly described?
Answer and explanation
Correct answer: Even digits less than 10
Every member of U is a decimal digit, every member is even, and every member is less than 10. Thus U is exactly the set of even digits below 10. Option B describes odd digits, and C excludes most listed values because they are not prime. Option D is too broad because it would include odd natural numbers as well. Hence A is correct.
