Which figure from the options completes the figure matrix below?

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
In each row, the flagpole turns 45° anticlockwise from one figure to the next. In row 3 the figure before the gap shows the flagpole with the flag at its lower-left end, so the missing figure shows the flagpole with the flag at its bottom end.

Why the other options are incorrect
Option (2) — Incorrect. It points the right way but is reversed: the flag is on the other side, so it is a mirror image.
Option (3) — Incorrect. It is the same as the figure before it in the row; it has not turned.
Option (4) — Incorrect. It is turned through 90° instead of 45°.
