a person could float most easily in ocean water that has which characteristic?\no warm\no fresh\no low…

Brief Explanations:

The higher the density of the water, the easier it is for a person to float. Salt - water is denser than fresh - water. Ocean water is salt - water. Warm ocean water has a lower density than cold ocean water in general, but saltier ocean water is denser. Low mass is not relevant to floating easily. A low freezing point is related to the salt content but not directly to ease of floating. Fresh water has lower density than ocean water, so a person floats less easily in fresh water.

Answer:

warm
