A rotation test like this asks us to mentally spin figure (I) by 45 degrees clockwise and then match the result against four candidates. The two traps to watch for are reflections (mirror images, which look similar but are not true rotations) and rotations in the wrong direction or by the wrong angle.
(P): every stroke of the original square pattern reappears turned by 45 degrees in the clockwise direction, the square's outline now sits as a diamond, and no part of the pattern is mirrored.
(Q): the pattern looks close, but it is the mirror image of the correct rotation, a flip rather than a turn, so left and right features are swapped compared to what a genuine rotation would produce.
(R): the pattern is turned by about 45 degrees, but in the counter-clockwise direction, the opposite of what the question asks for, so key strokes land on the wrong side of the diamond.
(S): parts of the pattern are rotated correctly, but other strokes are not shifted at all or shifted by a different amount, meaning it cannot be the result of one single rigid rotation.
Only (P) applies the same 45 degree clockwise turn to every part of the figure with no mirroring and no wrong-direction rotation, so it is the correct match for figure (I).
Let's summarize:
A genuine rotation keeps every stroke's shape and relative position the same, just turned about the centre.
Watch out for mirror images and rotations in the opposite direction, both are common wrong options.
So the figure that shows the 45 degree clockwise rotation of (I) is (P).
