Final answer:
The correct answer to which numbers in set A are elements of both set B and set C is the number 14, making option B (-2, 14) the right choice.
Step-by-step explanation:
The question asks which numbers in set A are elements of both set B and set C. Based on the provided information, set A AND B contains the numbers {14, 16, 18}. However, only the numbers from set A can be considered for the intersection with set B and C. Among the options given, only option B contains a number from set A that is also listed in the intersection of A AND B, which is the number 14. Therefore, the correct answer is that 14 is an element of set A that is also in both set B and set C.
