Final Answer :
A
Explanation :
The muscle that adducts (moves the arm towards the midline), extends (moves the arm back), and rotates (moves the arm in a circular motion) the arm is the latissimus dorsi. The pectoralis major muscle only adducts and flexes the arm, while the biceps brachii muscle only flexes and supinates the forearm. Therefore, the best choice is A, latissimus dorsi.
