What is the "raisin cake analogy" to the expanding universe intended to explain?

A) That as a raisin cake expands, every raisin moves away from every other raisin, just as galaxies move away from each other in an expanding universe.
B) That raisins, like galaxies, expand in size as the cake or universe expands.
C) That from within the raisin cake, you would see other raisins moving away from you only if you were on the central raisin, just as you see galaxies moving away only if you are in the center of the universe.
D) That the universe heats up as it expands, just as the raisin cake heats up as it bakes.
