have you learned matrix? if you have, use the \[(x ^{'} \ y ^{'}) =(\cos \theta & -\sin \theta \ \sin \theta & \cos \theta)(x \ y)\] if not, then you should firstly draw the angle ABC with the given coordinates. then rotate it 90 clockwise all the coordinates of thje angle is on the quadrant 1 ( where x and y are positives) if you rotate it 90 clockwise about the origin, the coordinates will move to quadrant 4 (where x is positive, and y is negative), so draw the coordinates that have been rotated. the answer must be the the one with all the x are positive and all thye y is negative
