Answer:
A. (0, -12)
Step-by-step explanation:
If a point is rotated 90° clockwise about the origin, its new coordinates can be found by swapping its x and y coordinates and then negating the new y-coordinate:
[tex]\Large\boxed{(x,y)\rightarrow (y,-x)}[/tex]
Therefore, if the coordinates of point A are (12, 0), then the coordinates of point A' after a clockwise rotation of 90° about the origin are:
[tex]\Large\boxed{\boxed{A'=(0,-12)}}[/tex]
