Answer: d. interubercular sulcus
Step-by-step explanation:
The intertubercular sulcus is the bicipital groove that separate the greater and lesser tubercle of the humerus bone. The pectoralis major is the thick, fan shaped muscle that is located on the chest of the body and ends in a flat tendon. In the end these muscles converge at the lateral edge of the bicipital groove of the humerus or intertubercular sulcus.
