Which set of structures passes through the jugular foramen?

• A CN IX, CN X, CN XI, and the inferior petrosal sinus ✓
• B CN VII, CN VIII, and the labyrinthine artery
• C CN IX, CN X, and the superior sagittal sinus
• D CN X, CN XII, and the ascending pharyngeal artery

Explanation

The jugular foramen transmits the glossopharyngeal, vagus and accessory nerves together with the inferior petrosal sinus, sigmoid sinus (forming the internal jugular vein), and posterior meningeal branches of the ascending pharyngeal artery. CN VII and CN VIII enter the internal acoustic meatus, CN XII leaves through the hypoglossal canal, and the superior sagittal sinus drains into the confluence of sinuses, not the jugular foramen.
