The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Ribs**: The human rib cage consists of 12 pairs of ribs. These ribs are categorized into three types: true ribs, false ribs, and floating ribs. 2. **Identifying True Ribs**: The first 7 pairs of ribs (from the 1st to the 7th pair) are known as true ribs. They are directly attached to the sternum (breastbone) via costal cartilage. 3. **Identifying False Ribs**: The next 3 pairs of ribs (the 8th, 9th, and 10th pairs) are referred to as false ribs. These ribs do not attach directly to the sternum but are connected to the 7th rib through cartilage. 4. **Identifying Floating Ribs**: The last 2 pairs of ribs (the 11th and 12th pairs) are known as floating ribs. They do not attach to the sternum or to the other ribs at all. 5. **Conclusion**: Therefore, false ribs are defined as the 3 pairs of ribs that follow the true ribs, which are the 8th, 9th, and 10th pairs. **Final Answer**: False ribs are the 3 pairs of ribs after the first 7 pairs (the 8th, 9th, and 10th pairs). ---
