In a factorial ANOVA,the null hypothesis for the interaction might look like ______.

A) H₀: µ_{upper × new} = µ_{upper × returning} = µ_{middle × new} = µ_{middle × returning}
B) H₀: µ_{upper × new} ≠ µ_{upper × returning} ≠ µ_{middle × new} ≠ µ_{middle × returning}
C) H₁: _{upper × new} = _{upper × returning} = _{middle × new} = _{middle × returning}
D) H_{1: upper × new} ≠ _{upper × returning} ≠ _{middle × new} ≠ _{middle × returning}
