The most suitable test for comparing two independent samples is the independent samples t-test. Option A, mixed ANOVA, is used when comparing more than two groups and testing for interactions between the groups and time. Option C, related samples t-test, is used when comparing two related groups (e.g. the same group before and after treatment). Option D, linear regression, is used to model the relationship between two continuous variables, which is not applicable in this scenario.
