Answer:
B
Explanation:
Since ice is less dense than water, it floats. This forms an ice cover sheet in cold regions such as in the poles. This insulates the water beneath from excessive heat loss hence preventing it from turning into ice too, This protects the marine life beneath. Also, water does not gain heat or loss it rapidly (due to its high heat capacity) hence offering a more or stable temperature range for marine life.
