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

Answer & explanation
Correct answer: option 1
The correct answer is Option (1) →
Three things change from figure to figure: the flagpole turns 45° clockwise each time; the small triangle moves one corner clockwise each time; and the black dot moves to the next side anticlockwise each time. So the next figure has the flagpole with the flag at its upper-left end, the small triangle at the top-right corner and the black dot at the middle of the top side.

Why the other options are incorrect
Option (2) — Incorrect. The other parts are right, but the flagpole has turned 45° anticlockwise instead of clockwise.
Option (3) — Incorrect. The other parts are right, but the flagpole is reversed: the flag is on the other side of its pole, so it is a mirror image of the right one.
Option (4) — Incorrect. The other parts are right, but the black dot has moved to the next side clockwise instead of anticlockwise.
