Why do we perform the ANOVA in experiments with more than 2 conditions of the IV rather than simply using multiple t-tests?

a) The omnibus ANOVA is not any better than running multiple t-tests.

b) The omnibus ANOVA shows us which group(s) are significantly different from the rest, unlike multiple t-tests.

c) Multiple t-tests would decrease our alpha level less than .05. The omnibus ANOVA increases our alpha level.

d)Multiple t-tests would increase our alpha level greater than .05. The omnibus ANOVA controls for this.
