Final answer:
The A. coracobrachialis is the muscle that adducts and flexes the arm. The other muscles listed, such as the teres major, pectoralis minor, and levator scapulae, are not primarily responsible for these actions.
Step-by-step explanation:
The Muscle that Adducts and Flexes the Arm
The question asks which muscle both adducts and flexes the arm.
Based on the information provided, the correct answer is the A. coracobrachialis.
The coracobrachialis muscle is responsible for the flexion and adduction of the arm.
Other muscles such as the teres major assists in adduction and medial rotation but it primarily extends the arm.
The pectoralis minor and levator scapulae are not primarily involved in the adduction and flexion of the arm.
The teres major is a muscle that assists in adduction and medial rotation, but its primary function is to extend the arm.
It is also not the correct answer since the question specifically focuses on the muscle that adducts and flexes the arm.
Therefore, the best choice given the options is the coracobrachialis for the action of adducting and flexing the arm.
