You write down a list (set) of elements which appear in ALL THREE sets A, B and C. If it is missing from any set, skip it. Then put your list between braces i.e. { and } (not [ and ]). If you want to check answers, do not diminish the importance of your answer by writing a letter. Write out (or at least copy and paste) the value of the answer.

Only the two elements in the boxes in the figure above are present in all three sets, so the intersection of the three sets is a set containing those two elements. Which choice is a set with only those two numbers?
