The choice identifying the common carotid arteries diverging into internal and external carotids is correct because the common carotid arteries serve as a critical pathway for blood flow to the head and neck. As they ascend the neck, each common carotid artery bifurcates into two branches: the internal carotid artery, which supplies blood to the brain and eyes, and the external carotid artery, which supplies blood to the face and neck. This anatomical feature is essential in understanding the blood supply to different regions of the head.

The other options do not accurately describe the anatomy of the common carotid arteries. While it is true that the right common carotid artery arises from the brachiocephalic trunk and the left originates from the aorta, indicating their presence in the neck, it is incorrect to say they are located solely in the neck since their branches extend beyond this region. Additionally, the common carotid arteries are not superficial; rather, they are deep vessels that are typically located lateral to the trachea and esophagus. Lastly, these arteries carry oxygenated blood from the heart to the brain and other areas, challenging the idea presented in the incorrect option regarding the transportation of deoxygenated blood.
