Ineed will give brainliest.
two similar triangles below are shown on the coordinate grid:

which set of transformations has been performed on triangle pqr to form triangle p′q′r′?

dilation by a scale factor of fraction 1 over 2 followed by reflection across the x-axis

dilation by a scale factor of 2 followed by reflection across the x-axis

dilation by a scale factor of fraction 1 over 2 followed by reflection across the y-axis

dilation by a scale factor of 2 followed by reflection across the y-axis

(it is not c.)
