Lead #3, positioned at the 2nd intercostal space below the left clavicle, is which lead name?

Explanation:
In this naming system, chest leads are represented by color-coded names that correspond to specific positions on the chest. The third chest position—the left upper chest just below the clavicle at the second intercostal space—is labeled as Lead Smoke. So describing Lead #3 at that exact spot aligns with Lead Smoke, making it the best answer. The other color-named leads refer to different chest locations, so they don’t match the described position.
