The Correct Option is A

Solution and Explanation

When soda water is opened, the carbon dioxide gas, which was dissolved under high pressure inside the bottle, escapes as the pressure is released. This is because the solubility of gases in liquids decreases with increasing temperature.
Therefore, the correct answer is "Decrease in solubility on increasing temperature."
