ANSWER

D. A'(-5,0), B'(0,9) and (2,6)

EXPLANATION

The coordinates of triangle ABC are A(0,-5), B(-9,0) and C(-6,2).

A rotation of 90° clockwise about the origin has the mapping,

$(x,y)\to (y,-x)$

Therefore the image triangle has vertices

A'(-5,0), B'(0,9) and C'(2,6)

The correct choice is D.
