Which of the Following Is the Correct Interpretation of Fisher's

Which of the following is the correct interpretation of Fisher's 100(1 − α) % confidence interval for μ_i - μ_j?

A) If the interval includes zero, the null hypothesis H₀: μ_i - μ_j = 0, is rejected at a significance level α.
B) If the interval does not include zero, the null hypothesis H₀: μ_i - μ_j = 0, is rejected at a significance level 100(1− α) %.
C) If the interval does not include zero, the null hypothesis H₀: μ_i - μ_j = 0, is rejected at a significance level α.
D) If the interval includes zero, the null hypothesis H₀: μ_i - μ_j = 0, is rejected at a significance level 100(1− α) %.
