pectoralis major
serratus anterior
coracobrachialis
deltoid
pectoralis minor

Explanation:

The serratus anterior muscle is located on the side of the chest. It originates from the outer surfaces of the upper 8 - 9 ribs and inserts into the medial border of the scapula. In the given diagram, based on its anatomical position (on the lateral chest wall near the ribs and scapula), the muscle labeled D matches the serratus anterior. The pectoralis major (B in the diagram) is the large fan - shaped muscle on the anterior chest. The coracobrachialis is a small muscle in the upper arm. The deltoid (A in the diagram) is the shoulder muscle. The pectoralis minor is a smaller muscle deep to the pectoralis major.

Answer:

Serratus anterior
