Triangle ABC is dilated with a scale factor of 4 and the center of dilation is the origin. If the coordinates of the vertices of ABC are A(4,8), B(12,8), C(16,20), what are the coordinates of the vertices of the image after the dilation?

Here are the answers:

A. A'(16,32), B'(48,32), C'(64,80)

B. A'(16,32), B'(48,8), C'(48,80)

C. A'(8,12), B'(16,12), C'(20,24)

D. A'(1,2), B'(3,2), C'(4,5)

to whoever give me the question because i have to turn this paper in tomorrow.
