- A1 and 2 only
- B2 and 3 only
- C1 and 3 only
- D1, 2 and 3
Explanation
Bar and pie diagrams use geometric figures (bars, sectors) to represent data and are classic diagrammatic forms. A pictogram represents data through pictures/symbols rather than diagrams, so per the official key only statements 1 and 2 count. Trap: pictogram looks 'diagrammatic' but is excluded here.
