What is the result of intersection(groupA, groupB)?

• A. {8,10}
• B. {3,6,9}
• C. {6,12}
• D. {6,8,12}

Answer: (C)

Intersection looks for values that appear in both groupA and groupB. To find it, identify the numbers that are present in both groups. The numbers common to both are 6 and 12, so the intersection is the set {6,12}. Other options contain numbers that aren’t shared by both groups, so they can’t represent the actual intersection.
