Which option will replace '?' in the given figure?

The correct answer is Option (1) → 

In each row, the third figure is the lines left over when the first two figures are laid on each other, that is, the lines that only one of them has: the hexagon is taken away from the hexagon with diagonals, and the square with diagonals from the square with diagonals and the cross. In the third row, the square with the curve is in both figures, so what is left is the pair of diagonals.
