B.
Normal mapping is used to make low-polygon objects look more detailed.
C.
Normal mapping increases the number of polygons required to define an object.
D.
Bump mapping is an application of normal mapping.
E.
Normal mapping is less efficient than bump mapping.

The answer is (b) Normal mapping is used to make low-polygon objects look more detailed.
