B. creating 2D logos

Explanation:

Contouring the lines is vital for recreating the same images and exact mathematical proportions. As such, it is most often used when making a map.

However, the software that makes contour lines will often be used to create 2D logos. Logos have to be recreated exactly as they are, since they are the permanent representation of the businesses, goods, companies, organizations, etc. This is why it is important to place lines as they are when creating logos.
