Final answer:
The adductors of the humerus are the pectoralis major and latissimus dorsi, both of which facilitate drawing the humerus towards the midline of the body.
Step-by-step explanation:
The adductors of the humerus are primarily responsible for drawing the humerus towards the midline of the body (adduction). According to the information provided, the muscles that serve this function include the pectoralis major and the latissimus dorsi. The pectoralis major is a thick, fan-shaped muscle located on the superior portion of the anterior thorax, originating from the sternum, and is involved in moving the humerus anteriorly. The latissimus dorsi, a broad, triangular muscle, is located on the inferior part of the back and also facilitates the adduction of the humerus as it moves the humerus inferiorly. Therefore, the correct answer to the question 'Which muscles are Adductors of the humerus?' is a. Pectoralis Major and Latissimus Dorsi.
