Rhomboid Minor has which action?

Explanation:
Rhomboid minor mainly pulls the shoulder blade toward the spine (retracts/adducts it) and helps rotate the scapula downward, which positions the glenoid cavity to support certain arm motions. It also acts to hold the scapula firmly against the thoracic wall during shoulder movement. That combination—retracting, downward-rotating, and fixing the scapula—best matches the muscle’s role, making the described action the correct choice. Protracting the scapula is done by serratus anterior, elevating the scapula is mainly the job of levator scapulae and upper trapezius, and depressing the scapula is typically caused by muscles like pectoralis minor or lower trapezius.
