Raises the shoulder and draws the scapula backwards.

Explanation:
Raising the shoulder and drawing the scapula backwards are actions produced by the trapezius. Its upper fibers elevate the shoulder (lifting it up), while the middle fibers pull the scapula toward the spine, which retracts it (draws it backwards). The deltoid mainly lifts the arm but doesn’t move the scapula backward. The platysma sits in the neck and has no effect on the scapula. The pectoralis major pulls the shoulder forward (protraction) and across the chest, not backward. So the trapezius best fits the described movement.
