Answer: A. Physical and reversible

The fizz is carbon dioxide gas escaping from the drink. The gas was dissolved in the liquid under high pressure; when the bottle is opened the pressure drops and the gas comes out. No new substance is formed, so it is a physical change, and gas can be dissolved back under pressure, so it is reversible.
