**Core Concept**
The act of deglutition, or swallowing, involves the coordinated movement of several anatomical structures to propel food from the mouth to the stomach. This process includes the movement of the **tongue**, **hyoid bone**, **larynx**, and **pharynx**.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general principle. During deglutition, the **elevation of the larynx** and **hyoid bone** occurs, which helps to prevent food from entering the airway. The **tongue** also plays a crucial role in swallowing by pushing food towards the pharynx.
