Type I error refers to a false positive, where the null hypothesis (in this case, the bull being harmless) is rejected when it is actually true. Choosing option B (running away for no good reason) would be a Type I error because the bull may actually be harmless and running away would be an unnecessary response. Option A is not a Type I error as feeling the bull's horns would mean the null hypothesis was false (i.e., the bull is not harmless). Option C is not related to the concept of Type I error.
