The experiment demonstrated that reducing caloric intake resulted in a number of positive outcomes, including increased lifespan, reduced incidence of cancer, and improved immune responses. These benefits were most pronounced in the group that had their caloric intake reduced by 65%, but were still observed in the groups with lesser reductions in caloric intake. Therefore, the best choice is D, all of the above.
