Answer: Option (b) is the correct answer.
Explanation:
When water or any other fluid contains high concentration of dissolved salts etc, it is known as salinity.
As the temperature rises, the water molecules start to expand. This expansion creates extra space where salt and other molecules get deposited. Hence, as compared to cold water, the warmer water can hold more salt or molecules.
Thus, the warmer the water, the higher will be its salinity.
Therefore, option (b) that is warm and high salinity is the correct answer.
