Answer: B
How to work it out
- Across each row the outline changes in the same way (solid, dashed or dotted); down each column the shape changes.
- The missing figure needs the bottom row’s shape and the right column’s outline.
Why the other options are wrong
- A: The trapezium is right, but its outline is solid, the left column's. Along a row the outline changes to dashed.
- C: The dashed outline is right, but a hexagon does not appear in this grid. The bottom row has the trapezium.
- D: The trapezium is right, but a dotted outline does not appear in this grid. It should be dashed.
- E: The dashed outline is right, but the octagon belongs to the top row. Down a column the shape changes to trapezium.
