Which intercostal spaces correspond to the upper to lower lobes of the lungs?

Explanation:
Lobar boundaries are mapped to the chest wall by the fissures that divide the lungs. The upper-to-lower boundary runs through specific interspaces: the upper edge near the 2nd intercostal space, the horizontal fissure on the right near the 4th intercostal space, and the lower edge near the 6th intercostal space. That pattern matches the option listing 2nd, 4th, and 6th intercostal spaces. The other sets don’t align with where the fissures that separate the lobes lie on the chest wall.
