what scale factor was used in dilation

Answer: (c) [tex]\bold{\dfrac{3}{4}}[/tex]
Step-by-step explanation:
Chooe any point I am choosing point W.
The W' is closer to C than W so the dilation is less than 1
The only answer choice that is less than 1 is option c.
Why is this the answer? because the side lengths are proportional
[tex]\dfrac{CW'}{CW} = \dfrac{WX'}{WX}= \dfrac{3}{4}[/tex]
