What is the primary function of a syringe?

The primary function of a syringe is to measure and transfer liquids, making it essential in various fields such as medicine, laboratory work, and cooking. Syringes have a cylindrical barrel with a plunger that creates suction, allowing for precise measurement and administration of liquids. This capability is particularly significant in medical settings where accurate dosage is crucial for patient safety and effective treatment.

While some syringes can hold solid medicine, their design and use are specifically tailored for liquids, which makes option C the most fitting answer. The other options relate to functions that a syringe is not designed to perform, focusing instead on different applications or substances that do not align with the syringe's primary use.
