Of the options given, Orange Juice is a solution. A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent). In orange juice, the sugars and other components are dissolved in water, making it a uniform mixture. Air, on the other hand, is a mixture of gases, not a solution in the typical sense.
Orange juice from concentrate would be a solution, although real orange juice is neither a solution or a suspension. The major difference between solution and suspension is that a solution is a homogeneous mixture, and a suspension is heterogeneous.
As orange juice being an acidic solution, it turns blue litmus into red.
