which muscle is highlighted?
serratus anterior
deltoid
pectoralis minor
rectus abdominis

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 anterior surface of the medial border of the scapula. Its main function is to protract the scapula and rotate it upward. In the image, the highlighted muscle's position (along the ribcage, connecting to the scapula) matches the anatomical location of the serratus anterior. The deltoid is on the shoulder, the pectoralis minor is a smaller muscle under the pectoralis major (more central - chest area), and the rectus abdominis is the "six - pack" muscle in the mid - abdomen.

Answer:

serratus anterior
