Each cell shows a small orange shape inside a larger white shape. Look for the link between neighbouring cells in a row. Which figure is missing?

In every row the small inner shape of a cell becomes the large outer shape of the next cell, and the inner shape of the last cell is the outer shape of the first cell. In the bottom row the outer shape must be a hexagon (inside the square) and its inner shape must be a pentagon (the first outer shape): (b). (a) has the two shapes swapped, (c) has the wrong inner shape and (d) the wrong outer shape.
