The terrain may be classified as rolling terrain if the cross slope of land is A. upto 10% B. between 10% and 25% C. between 25% and 60% D. more than 60%

The correct answer is: B. between 10% and 25%

A rolling terrain is a type of terrain that is characterized by gentle slopes. The cross slope of land is the slope of the land in a horizontal direction. A cross slope of land that is between 10% and 25% is considered to be rolling terrain. This type of terrain is often found in areas that have been glaciated, such as the Midwest of the United States. Rolling terrain is generally considered to be good for agriculture and development.

Option A: Up to 10% is considered to be flat terrain.
