Rotation of 90 degrees counterclockwise about the origin

Answer 2

@steve816 last one please

Answer 3

?

Answer 4

it cant be C, because neither shape is on the y-axis, and it cant be A, because reflections are always facing each other, and 90 degrees is too short of a turn, so by process of elimination, it must be B.
