The relevant hypotheses tested are H0: μ1-μ2 = 0 versus H1: μ1-μ2 ≠ 0, which is represented by option C. This is a two-tailed test. Options A and B are incorrect because they represent one-tailed tests. Option D is incorrect because it assumes that the means are not equal (μ1 ≠ μ2), which is not stated in the scenario.
