Answer: C. Bodies of water would freeze from the bottom up.
Step-by-step explanation:
The water in the form of ice exhibit low density as compared to the water in the liquid form. Hence, the ice will float over the surface of water if ice is kept in water.
But according to the given condition, the solid water that is actually the ice will be denser than the liquid water. Thus the solid water will sink at the bottom of the liquid water. As a consequence the bodies of water would freeze from the bottom.
