Studies have found that the planum temporale, which is an area in the temporal lobe associated with language processing, is larger in the left hemisphere in about 65% of human brains. The other structures mentioned (Heschl's gyrus, frontal operculum, and Broca's area) are also involved in language processing, but their lateralization varies across individuals. Option E (both C and D) is not the correct answer because only option B (planum temporale) is consistently found to be larger in the left hemisphere.
