Solution
The correct option is E II and III Limited or no sunlight in deeper waters keep the temperature lower in the regions making it suitable for fishes when surface water become warm due to increasing in average global temperature. Likewise, higher latitudes maintain lower temperatures due to the angle of irradiance. Salinity does not affect the temperature range of water bodies. Thus, the correct answer is E.
