• B. Oxygen ($O_2$)
• C. Carbon dioxide ($C{O}_2$)
• D. Argon ($Ar$)

The correct option is C

Carbon dioxide ($C{O}_2$)

The fizz that bubbles up when you open a bottle of soda is carbon dioxide gas ($C{O}_2$). Soft drink manufacturers add fizz by dissolving carbon dioxide into the water at high pressures.
