The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the origin of vertebrate lungs. This refers to the anatomical and developmental aspects of how lungs in vertebrates are formed. 2. **Identifying the Structures Involved**: In vertebrates, the respiratory system begins with the trachea, which is commonly known as the windpipe. The trachea is a crucial structure that facilitates the passage of air into the lungs. 3. **Tracing the Path of Air**: The air enters the respiratory system through the pharynx. The pharynx is divided into three parts: - Naso-pharynx - Oropharynx - Hypopharynx 4. **Connecting the Dots**: The trachea branches off from the pharynx, indicating that the lungs develop from structures associated with the pharynx. 5. **Conclusion**: Therefore, the correct answer to the question "Vertebrate lungs arise from" is the pharynx. ### Final Answer: Vertebrate lungs arise from the pharynx. ---
