____ are concentrated aqueous preparations of a sugar with or without flavoring agents and drugs.

• A. Elixirs
• B. Tinctures
• C. Syrups
• D. Solutions

Answer: (C)

Syrups are concentrated aqueous solutions of sugar, often with flavoring agents and drugs. The defining feature is their high sugar content, which makes the mixture thick and sweet, helping mask tastes and acting as a preservative to some extent. Simple syrups serve as a base for many medicated syrups, where drugs are dissolved or suspended in a sugar solution and additional flavors or colors can be added.

Elixirs are hydroalcoholic solutions, not concentrated sugar solutions, and they rely on alcohol to dissolve and preserve ingredients, plus flavoring—so the sugar-concentration focus isn’t the defining trait. Tinctures are alcoholic extracts of plant materials, again not focused on a sugary base. Solutions is a broad term for any homogeneous mixture and doesn’t specify the sugar-rich formulation described here.

So the description fits syrups best because it centers on a concentrated sugar solution used as a vehicle for flavoring agents and drugs.
