Which statement about bump mapping and normal mapping is true?

A.
Normal mapping makes objects look less detailed.
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.

Explanation:

A normal map is uses RGB information .The RGB information tells the 3D application about the exact location/direction of the surface normals.It is through the  orientation of the surface normals the polygon are shaded by the 3d application.In simple words,Normal Mapping makes the Polygon look more derailed by the use of RGB information

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.

i think its c but i'm not
