Which of the option figures will take the place of the question mark and continue the series?

Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →
Two things change from figure to figure: the hooked line turns 90° anticlockwise each time, and the small triangle moves one place clockwise round the edge of the box each time. So the next figure has the hooked line with the hook at its lower-right end and the small triangle at the middle of the top side.

Why the other options are incorrect
Option (1) — Incorrect. The small triangle is right, but the hooked line is reversed: the hook bends to the other side, so it is a mirror image of the right one.
Option (2) — Incorrect. The small triangle is right, but the hooked line has turned 90° clockwise instead of anticlockwise.
Option (3) — Incorrect. The hooked line is right, but the small triangle has moved one place anticlockwise instead of clockwise.
