Correct answer: A
Solution: Identify the region common to the circle (strong), the square (intelligent), and the triangle (tall).
16 — inside the triangle only (tall only).
11 — inside the square and triangle but outside the circle (tall and intelligent only).
7 — inside the circle and triangle but outside the square (strong and tall only).
12 — inside the circle and square but outside the triangle (strong and intelligent only).
13 — inside the circle only (strong only).
9 — inside the square only (intelligent only).
4 — inside the circle, the square, and the triangle (strong, intelligent, and tall).
Therefore, the number that represents people who are strong, tall, and intelligent is 4.
