**Core Concept:** The external carotid artery is a major artery of the neck that supplies blood to the head and neck. It branches into several terminal arteries, each supplying specific regions.

**Why the Correct Answer is Right:** The correct answer represents the primary divisions of the external carotid artery, which are:

1. **Option C: The internal carotid artery (ICA)**: This artery branches off the external carotid artery and supplies blood to the brain. The ICA is part of the cerebral circulation, ensuring essential blood supply to the brain and brainstem.
2. **Option D: The ophthalmic artery (OA)**: The OA arises from the external carotid artery and supplies blood to the eye and its structures, such as the eyelids, forehead, and nose.
3. **Option B: The maxillary artery (MA)**: The maxillary artery is another branch of the external carotid artery that supplies blood to the face, especially the cheek region.

**Why Each Wrong Option is Incorrect:**

1. **Option A: The facial artery (FA)**: Although the FA is a branch of the external carotid artery, its primary distribution is to the face, particularly the temporal and mandibular regions, not the neck or head.
2. **Option A (repeated): The facial artery (FA)**: This option duplicates the description of Option A and is thus incorrect as well.

**Clinical Pearl:** Understanding the anatomy of the external carotid artery and its branches is essential for surgeons, anesthesiologists, and physicians treating patients with head and neck injuries or conditions.

**Correct Answer:** C. Internal carotid artery (ICA), D. Ophthalmic artery (OA), B. Maxillary artery (MA)
