The ability to rotate a model so that it looks 3-dimensional is an advantage of computer modeling. The image below, for example, provides views of the molecule taxol from three different angles.

What is the function of the colors in the computer model of taxol shown above?
A.
The colors are arbitrary and have no precise meaning when interpreting the model.
B.
The colors are showing the actual colors of different elements in the molecule.
C.
The colors are used to show which atoms have a ring shape and which are spheres.
D.
The colors are added by the programmer to identify different elements in the molecule.
