Solution

The correct option is A Greater than 1
Concept: Original length×Scale factor=New length

Scale factor=New lengthOriginal length

As Sara wants to enlarge the stick that means
New length > the original length.

New lengthOriginal length>1

Scale factor > 1

For example:
To enlarge the length from 2 inch to 4 inch, scale factor is 2 which is greater than 1.
