I think the correct answer is B. The output clearly shows that Adv and Bev are the only factors with statistical significance at the 95% level.

But what about the lack of P-values in the MINITABTM output? Doesn't that mean we can't conclude anything?

I disagree, I believe the correct conclusion is D) The response level is statistically concluded to only need the Adv and Bev factors set at the low level to get the largest response rate.
