An essential nutrient is a nutrient that the body cannot make itself and must therefore be supplied through the diet. Option A is incorrect because scurvy is caused by a deficiency of vitamin C, not vitamin E. Option B is incorrect because phytochemicals are produced by plants, not animal cells. Option C is also incorrect because the human body cannot make iron, copper, or zinc, but rather must obtain these minerals through the diet.
