Correct: C — the structure marked drains into the superior petrosal sinus. In a left retrosigmoid approach to the upper cerebellopontine angle for trigeminal microvascular decompression, the superior petrosal vein (Dandy's vein) is the key venous structure and it empties into the superior petrosal sinus along the petrous ridge. Option A, the transverse sinus, option B, which names the vein itself rather than its outflow, and option D, the straight sinus, are all incorrect destinations.
