The exercise that primarily targets the elevation of the shoulder complex is the barbell shrug. This movement specifically focuses on the trapezius muscles, which are crucial for the elevation of the scapulae, or shoulder blades. When performing a barbell shrug, the lifter stands upright holding a barbell at hip level and elevates the shoulders towards the ears, thereby engaging the upper portion of the trapezius muscle. This action effectively isolates the muscles responsible for shoulder elevation without involving significant movement at the elbows or wrists.

In contrast, the other exercises listed involve different movements that do not primarily target shoulder elevation. The deadlift focuses on overall posterior chain strength, the overhead press emphasizes shoulder stability and pressing movement but includes a different range of motion, and the dumbbell fly is primarily a chest exercise that works the pectoral muscles without significantly engaging the shoulder elevation. Therefore, the barbell shrug is specifically designed to enhance shoulder elevation, making it the most appropriate choice for this particular question.
