Explanation:

The triceps muscle is located at the back of the upper - arm. Its main function is to extend the elbow joint, which means straightening the elbow. Flexing the shoulder is mainly the job of other muscles like the deltoid and pectoralis major. Contracting the biceps is an action related to the biceps muscle itself, not the triceps. Bending the elbow is a function of the biceps and other flexor muscles. Moving the wrist is mainly controlled by the forearm muscles.

Answer:

Straightening the elbow
