The ANOVA table shows there were 2 levels of advertising and 3 levels of price used, with a total of 6 different treatments. Therefore, option C is correct. Options A and B are incorrect as they do not match the number of levels used for each factor. Option D is also incorrect as it only restates the total number of treatments without specifying the number of levels used for each factor.
