Rib related to the oblique fissure of the lung posteriorly?

Explanation:
The main feature tested is the posterior landmark of the oblique fissure, which is the diagonal fissure separating the upper and lower lobes of the lung. On the back, this fissure lines up roughly with the fourth rib, so the rib that relates to the oblique fissure posteriorly is the fourth. This makes the fourth rib a useful posterior landmark for where the fissure lies, helping with palpation, imaging, and auscultation directions.
