No answer provided yet.

I would use a 1-way ANOVA to detect the difference between means. When I run the analysis I see a p-value of .025, suggesting there is a difference between means at the .05 level. The F-statistic and degrees of freedom are  F 4.70(2,18) p = .025 .

While you would then most likely need to run a follow-up pair-wise comparison test to see which means are different, in looking at the Confidence Intervals of the means, I'd say that B is different than C, while the other 2 combinations are too close to call.
