C. Cross-sectional studies are not good representation of inter-individual differences
Explanation:
Cross sectional research method is not representative enough. if another cross sectional study is conducted, it won't be surprising that the results might show that younger adults perform better than older adults because the representative selected for each age group were just hand picked and it can be used to generalize for the whole younger population.
