Solution

The correct option is C Being bad conductor of heat, ice protects the water from freezing underneath.
Life is present even below the sheet of ice in Antarctica because the ice bed acts as an insulator and thus, the temperature of water beneath it is not very low. So, aquatic life can sustain there as water beneath the ice does not freeze.
So, the correct answer is 'Being bad conductor of heat, ice protects the water from freezing underneath.'.
