Three things change from box to box here. Which option obeys all three rules for the next box? Four boxes in a row, then a fifth box marked with a question mark. Box 1: a shaded heptagon, with a dot at the top-left corner. Box 2: an unshaded hexagon, with a dot at the top-right corner. Box 3: a shaded pentagon, with a dot at the bottom-right corner. Box 4: an unshaded square, with a dot at the bottom-left corner.

Correct answer: D

The shape loses one side each time: heptagon, hexagon, pentagon, square, so next comes a triangle.
Shaded and unshaded shapes alternate, starting shaded, so the fifth shape is shaded.
The dot moves 2 places clockwise round the box each time (the 4 corners and 4 edge midpoints are the 8 places): from the bottom-left corner it goes to the top-left corner.
Figure 4 shows a shaded triangle, with a dot at the top-left corner.

Worth noting

Track one element at a time across all four boxes, and check each option against every rule; each wrong figure here breaks exactly one of them.
