The correct rejection region for a left-tailed test (μ < 60) at α = 0.05 with a t-distribution is where the test statistic t is less than the critical value, which for a sample size of 100 (and thus 99 degrees of freedom, which approximates to infinity for practical purposes) is approximately -1.6604. This aligns with option B, indicating a test for a mean less than the hypothesized mean of 60.
