B. Nasal chambers from entry of food
C. Larynx from entry of food
D. Teeth from caries

Answer

### Step-by-Step Solution:

1. **Understanding the Function of the Epiglottis**: The epiglottis is a flap of cartilage located at the root of the tongue. Its primary function is to prevent food and liquids from entering the trachea (windpipe) during swallowing.

2. **Identifying the Structures Involved**:
- The **esophagus** is the tube that carries food from the mouth to the stomach.
- The **larynx** is part of the respiratory system and is located above the trachea. It plays a crucial role in breathing and sound production.

3. **Analyzing the Options Given**:
- **Option A**: Esophagus from entry of air - Incorrect, as the esophagus is meant for food, not air.
- **Option B**: Nasal chambers from entry of food - Incorrect, as the nasal chambers are not directly involved in the swallowing process.
- **Option C**: Larynx from entry of food - Correct, as the epiglottis covers the larynx during swallowing to prevent food from entering the trachea.
- **Option D**: Teeth from caries - Incorrect, as the epiglottis does not protect teeth.

4. **Conclusion**: Based on the function of the epiglottis and the analysis of the options, the correct answer is **Option C: larynx from entry of food**.
