Determine which of the answer options complete the figure matrix given below.

Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →


Each row uses the circle, the triangle and the square once. In row 3 each figure is one shape with another shape inside it: a circle inside a square, then a triangle inside a circle. The shape that has not yet been the outer one is the triangle, and the shape not yet inside is the square, so the missing figure is a square inside a triangle.
