which muscle is responsible for rotation of the scapula and protraction of the shoulder?
serratus anterior
subclavius
pectoralis minor
trapezius

Explanation:

The serratus anterior muscle is known for its role in rotating the scapula and protracting the shoulder. The subclavius primarily depresses the clavicle. The pectoralis minor depresses the shoulder and downwardly rotates the scapula. The trapezius has functions like elevating, retracting, and rotating the scapula but its main role isn't specifically protraction of the shoulder in the way the serratus anterior is.

Answer:

Serratus Anterior
