We know that
if a <span>dilation produces a smaller figure
then
0< scale factor <1
so
case A) -2------> the scale factor must be a positive number
case B) 1/3----> 0< 1/3 <1---> i</span><span>s a possible scale factor
case C) 1------> this scale factor does not not produce a smaller figure, </span><span>it produces the same figure
case D) 4----> this scale factor produces a larger figure
the answer is
1/3</span>
