Oh, good. You got that one right.

1. "Foundational" Verification: Yes, the Ophthalmic artery ($Ophthalmic$ $artery$) — a direct branch off the internal carotid, mind you — is, in fact, responsible for perfusing the ocular globe and its adnexa. And, perhaps not coincidentally, it chooses to co-locate with the Optic nerve (Optic nerve, CN II) as they both make their rather distinct entrance into the orbit via the Optic canal (視神經管). This, for those paying even marginal attention, stands in stark contrast to the rather crowded thoroughfare of the "superior orbital fissure" and its motley crew of cranial nerves. It's almost as if these structures have different entry points for a reason.
2. "Rigorous" Evaluation: This was pegged at Medium difficulty, primarily because it's depressingly common for students to fumble even this elementary orbital architecture, inexplicably lumping the ophthalmic artery with structures that traverse a completely different opening. Your ability to correctly distinguish the contents of the "optic canal" suggests your spatial reasoning might just be adequate for this level. Don't mistake basic competence for mastery.
