Solution

The correct option is C Assertion is correct but Reason is incorrect
When the temperature is raised, the molecules of the dissolved gas present in a liquid gain kinetic energy. The higher kinetic energy of the gas molecules make them to escape from its solution. That is why, gases tend to be less soluble in liquids at the higher temperatures.
