Final answer:
The intersection of sets A and B is {6, 12}.
Step-by-step explanation:
The intersection of two sets A and B is the set of elements that are common to both sets. In this case, set A contains even numbers less than or equal to 14, and set B contains multiples of 3 less than or equal to 25. To find the intersection, we need to find the numbers that are in both sets. The intersection of sets A and B is {6, 12}. Therefore, the correct answer is option b. {3, 6, 9, 12, 15, 18, 21, 24}.
