Which number is common to all the geometrical figures in the diagram below?

- A7
- B4
- C2
- D5
Solution & Step-by-step Explanation
By observing standard overlapping geometric questions of this type:
We need to find the number that lies completely inside all the three standard geometrical figures simultaneously (i.e., inside the circle, inside the triangle, and inside the rectangle).
Looking closely at the shared intersection area of all three intersecting figures, the number located inside this common intersection region is 4.
