**Core Concept**
The abducens nerve (cranial nerve VI) is responsible for the innervation of the lateral rectus muscle, which is responsible for outward gaze. Damage to this nerve results in impaired outward movement of the affected eye.

**Why the Correct Answer is Right**
The lateral rectus muscle is the primary muscle responsible for outward gaze. When the abducens nerve is damaged, the muscle is paralyzed, leading to inability to abduct the eye (move it outward). To confirm the damage, the physician would ask the patient to attempt to move her right eye outward. If the abducens nerve is damaged, the eye would be unable to move outward, whereas the medial rectus muscle, which is responsible for inward gaze, would still function normally.

**Why Each Wrong Option is Incorrect**
**Option A:** Inward movement of the eye is controlled by the medial rectus muscle, which is not affected by damage to the abducens nerve.
**Option C:** Downward movement of the eye is controlled by the inferior oblique and inferior rectus muscles, which are not innervated by the abducens nerve.
**Option D:** Down and out movement of the eye is a combination of outward and downward movement, and the question specifically asks for outward movement to confirm abducens nerve damage.

**Clinical Pearl / High-Yield Fact**
Remember that the abducens nerve is the only cranial nerve that innervates a muscle that is responsible for moving the eye in one direction (outward). This makes it a crucial nerve to assess in patients with suspected cavernous sinus thrombosis or other conditions that may affect the pituitary gland or surrounding structures.

✓ Correct Answer: B. Outward
