Correct Answer:
A. Water
This question asks about common solvents, specifically in the context of soft drinks. Understanding the properties and uses of different solvents is key.
- Water is the correct answer. Water is known as the 'universal solvent' and is the primary component of virtually all soft drinks, dissolving sugars, flavorings, and other ingredients.
- Acetone (B) is a strong organic solvent used in industrial applications and nail polish remover; it is toxic and not safe for consumption.
- Ether (C) is a highly flammable organic solvent, historically used as an anesthetic, and is not used in beverages.
- Alcohol (D) is a solvent, but it is not the primary solvent in *soft drinks*, which are non-alcoholic beverages.
Therefore, water is the most common and essential solvent in soft drinks.
