Explanation

To answer the question regarding the location of the vocal cords, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Respiratory System**: The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide. It consists of various structures that facilitate this process.

2. **Air Pathway**: When we inhale, air enters through the nostrils and moves into the nasal chamber. From there, it passes through the pharynx, which serves as a common passage for both air and food.

3. **Identifying Key Structures**: After the pharynx, the air moves into the larynx. The larynx is a crucial structure in the respiratory system, often referred to as the voice box.

4. **Function of the Larynx**: The larynx contains the vocal cords (or vocal folds), which are essential for sound production. This is where the air passing through can create sound, allowing us to speak and vocalize.

5. **Conclusion**: Based on the information gathered, the vocal cords are located in the larynx. Therefore, the correct answer to the question is **option B: Larynx**.
