Adilation produces a smaller figure. which is a possible scale factor? –2 1/3 1 4

We know that
if a 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---> is a possible scale factor
case C) 1> this scale factor does not not produce a smaller figure, it produces the same figure
case D) 4> this scale factor produces a larger figure

the answer is
1/3
