Aggregation over subjects is the most applicable option in this case. This is because researchers pool data from different individuals or subjects, and base their conclusions on group averages. Aggregation over measures refers to combining data from different measures, while aggregation over stimuli involves pooling data from different stimuli. Aggregation over trials involves combining data from different trials or repeated measurements. Hence, the most appropriate option is C, aggregation over subjects.
