The alternative hypothesis in testing the difference between the means of two groups often states that there is a difference, but does not specify the direction or magnitude. Therefore, "µ₁ - µ₂ ≠ 0" correctly represents an alternative hypothesis, indicating that the means of the two groups are not equal. The symbol "≠" is used to denote "not equal to," but due to a typographical error, it appears as "0" in option B. Understanding the context, option B is intended to mean "µ₁ - µ₂ ≠ 0".
