The correct answer is: 1/6
Further explanation:
We have to find the scale factor.
for this purpose we will check each option one by one.
We already know that reduction is involved which means that the scale factor will be a fraction.
Option A: 1/6
![18*\frac{1}{6}=3](https://tex.z-dn.net/?f=18%2A%5Cfrac%7B1%7D%7B6%7D%3D3)
Using this scale factor the side of parallelogram is reduced to 3 from 18mm
So,
The correct answer is: 1/6
