If Earth's Oceans Were Fresh Water, Would Fluctuations in Global

If Earth's oceans were fresh water, would fluctuations in global temperatures be more or less pronounced?

A) If the oceans were fresh water, fluctuations in global temperatures would be much more pronounced as can be witnessed by the melting of the polar ice caps to fresh water.
B) If the oceans were fresh water, the oceans' specific heats would be greater and this would help towards moderating global temperatures.
C) Fluctuations in global temperatures are not dependent on the ocean being salt water rather than fresh water.
D) If the oceans were fresh water, both their densities and specific heats would decrease, thus having a more pronounced effect on fluctuations in global temperatures.
