Which vessel is the major trunk that supplies the right side of the head and arm?

Explanation:
The major arterial trunk supplying the right side of the head and upper limb comes off the aortic arch and splits into the right common carotid artery (to the head and neck) and the right subclavian artery (to the upper limb). This trunk is the brachiocephalic trunk, also known as the innominate artery. The other vessels listed don’t fit this role: the left pulmonary artery goes to the lungs, the left common carotid supplies the left side of the head/neck, and the anterior interventricular artery serves the heart.
