Should the Specific Heat of Your Automobile's Radiator Fluid Be

Should the specific heat of your automobile's radiator fluid be as high as possible or as low as possible? Why?

A) A higher specific heat radiator fluid would be more effective at distributing the heat to different parts of the engine so it doesn't all build up in one place.
B) A lower specific heat would mean that it is starting at a low temperature, and has to heat up to a much higher temperature before it boils away.
C) A higher specific heat radiator fluid would be more effective at absorbing heat from the engine, so that it doesn't melt.
D) A lower specific heat radiator fluid means that its molecules will not form a thick solution, but rather will get "thinner" as it is heated so that it won't block up the radiator.
