Question

a person could float most easily in ocean water that has which characteristic?
warm
fresh
low mass
low freezing point

Explanation:

Floating depends on buoyancy, which relates to water density. A lower freezing point in ocean water indicates higher dissolved salt content, which increases water density. Denser water provides greater buoyancy, making it easier to float. Warm water is less dense, fresh water has lower density than saltwater, and low mass of water is irrelevant to buoyancy for floating.

Answer:

low freezing point
