- A19
- B5
- C17
- D12
Solution & Step-by-step Explanation
According to the diagram, the rectangle represents persons who know English. To find the individuals who can speak English exclusively, we must find the region that lies only inside the rectangle and outside all other figures (triangle, square, and circle). The region labelled '12' is the only one satisfying this condition. Therefore, 12 individuals can speak English exclusively.
