At the end of the summer, Jasmine harvests the corn from each section. She finds that the section given "fertilizer b" yielded the most corn; the section given "fertilizer a" yielded slightly less corn; and the section given "fertilizer c" yielded, by far, the least amount of corn. From this information, Jasmine concludes that "fertilizer b" is the best at increasing crop yields. Is Jasmine's conclusion scientifically valid? A. Yes, because "fertilizer b" increased her crop yield. B. No, because the crop yields were all equal. C. No, because the different sections of her land have different characteristics. D. No, because the different sections of her land were not equal in area.
