Correct Answer: Option B
Explanation

The structure that could result in choking when talking and eating at the same time is the epiglottis.
The epiglottis is a flap-like structure located at the base of the tongue, near the entrance of the windpipe (trachea). Its primary function is to prevent food and liquids from entering the trachea and lungs during swallowing. When you swallow, the epiglottis covers the opening of the trachea, directing food and liquids into the esophagus, which leads to the stomach. This prevents choking and aspiration of food into the respiratory system.
