Answer: c. Point B has an elevation less than 2750 feet.
Explanation:
The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.
Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.
