C) a one-way between-subjects ANOVA
D) a two-independent-sample t test and a one-way between-subjects ANOVA

This study involves dividing participants into groups that will engage in different levels of exercise, which creates different treatment conditions. The researcher needs to compare the mean caloric intake of participants across the different exercise groups, which can be achieved through a one-way between-subjects ANOVA. This statistical design allows the researcher to test whether there is a significant difference in mean caloric intake between the different exercise groups, while controlling for other potential factors that might affect caloric intake. A related-samples t-test and a two-independent-sample t-test are not appropriate because they are designed for different types of study designs where the treatments are either compared within the same group or between two separate groups, respectively.
