Which figure from the options completes the figure matrix below?

Answer & explanation
Correct answer: option 2
The correct answer is Option (2) →
Every row and every column has one hexagon, one triangle and one diamond, and each of the marks inside (plus sign, small circle and cross) also appears once in every row and every column. Row 2 still needs a diamond and a cross, so the missing figure is a diamond with a cross inside.

Why the other options are incorrect
Option (1) — Incorrect. Both the shape and the mark are already used in this row and column.
Option (3) — Incorrect. Column 2 already has a triangle, so the gap cannot have one.
Option (4) — Incorrect. Column 2 already has a hexagon, so the gap cannot have one.
