From which major arterial vessel does the right common carotid artery originate?

Correct answer is C). The right common carotid artery originates from the truncus brachiocephalicus, also known as the brachiocephalic trunk. This major arterial trunk arises directly from the aortic arch and gives rise to the right common carotid artery. A) Incorrect. While the left common carotid artery arises directly from the aortic arch, the right common carotid artery has a different origin. B) Incorrect. The right common carotid artery does not branch directly from the right subclavian artery; it shares its origin with the right subclavian artery from the truncus brachiocephalicus. D) Incorrect. The right common carotid artery does not directly emerge from the right internal carotid artery; it has a separate origin from the truncus brachiocephalicus.
