Which nucleus is to vision as which nucleus is to auditory inputs?

Explanation:
The idea being tested is how the thalamus routes different sensory modalities. Visual information is relayed through the lateral geniculate nucleus (LGN) before reaching the primary visual cortex, while auditory information is relayed through the medial geniculate nucleus (MGN) before reaching the auditory cortex. So the parallel pair is LGN for vision and MGN for hearing. Other options mix modalities: the ventral posterolateral nucleus (VPL) and ventral posteromedial nucleus (VPM) handle somatosensory information from the body and face, respectively, not auditory input; pairing vision with a somatosensory nucleus or auditory input with a somatosensory nucleus would not fit the actual auditory pathway.
