Which property of water enables fish and other organisms to survive a cold winter in a frozen pond?

a. water becomes more dense as it freezes, increasing the amount of cohesion and slowing the evaporation rate of water.
b. water becomes less dense as it freezes, so ice floats and acts as an insulator, allowing the water underneath to remain a liquid.
c. the hydrogen bonds in water molecules come apart as water freezes, causing dissolved oxygen to be released into the environment.
d. the adhesion of water molecules increases as water freezes, so ice has a higher concentration of dissolved substances than liquid water.
