Option A is not supported by the findings of the study as there were no twins who were raised entirely apart from one another. Option B is partially true as the study found that genetics accounts for about 50% of our personality traits. Option C is also partially true as the study found that the extent of similarities and differences between identical twins raised apart varied depending on the specific traits being examined. Therefore, option D is the correct choice as it accurately reflects the findings of the Minnesota Twin Family study.
