Correct answer: B — Axillary nerve / suprascapular nerve / lateral pectoral nerve / subscapular nerves

The glenohumeral (shoulder) joint receives innervation from: suprascapular nerve (posterior superior) / axillary nerve (inferior) / lateral pectoral nerve (anterior) / and subscapular nerves. This follows Hilton's law. Shoulder surgery analgesia requires blocking at least the suprascapular and axillary nerves (interscalene block covers all).
