Answer : option A
In a dilation with a scale factor of 3/4 the image is the preimage
In a similar figures, the ratio of the corresponding sides of the figure is called as scale factor. When scale factor is less than 1 then the image is smaller than the preimage. When scale factor is greater than 1 then the image is larger than the preimage.
Here we are given with scale factor 3/4, that is less than 1
So the image is smaller than and along the same ray as the preimage
