The three mixtures that are solutions are:

1. Air: Air is a solution of various gases. It is mainly composed of nitrogen and oxygen, with small amounts of other gases like carbon dioxide, argon, and others.

2. Sea water: Sea water is a solution of water and various salts and minerals. It contains a significant amount of sodium chloride (table salt), but also contains other substances in smaller amounts.

3. Fizzy lemonade: Fizzy lemonade is a solution of water, sugar, lemon flavor, and carbon dioxide gas (which gives it its fizz).

Cloud and mud are not solutions. A cloud is a suspension of water droplets or ice crystals in the air. Mud is a mixture of water and soil, but the soil does not dissolve in the water, so it is not a solution.
