A confidence interval that does not include 0 suggests that there is a significant difference between the two means, leading to the rejection of the null hypothesis that there is no difference ($\mu _ { 1 } - \mu _ { 2 } = 0$). Option A's interval does not include 0, indicating a significant difference.
