The Alternative Hypothesis for a One-Way Randomized ANOVA States That $\mu$

The alternative hypothesis for a one-way randomized ANOVA states that:

A) H₀: $\mu$ ₁ = $\mu$ ₂ = $\mu$ ₃.
B) H₀: $\mu$ ₁ $\not =$ $\mu$ ₂ $\not =$ $\mu$ ₃.
C) H_a: $\mu$ ₁ = $\mu$ ₂ = $\mu$ ₃.
D) H_a: at least one $\mu$ differs from the others_.
