Answer:
Option C.
Explanation:
Consider the below diagram has been attached with this question.
It is given that square QRST is dilated by a scale factor of three about the center of the square to create square Q'R'S'T'.
If line passes through the center of dilation, then nothing will change. It means both lines coincide each other.
The line WX passes through the point O which is the center of dilation, then after dilation by factor 3 the line W'X' coincide the line WX.
It means, the line W'X' will pass through points W and X.
Therefore, the correct option is C.
