A meal plan should suit your family's dietary needs, so B wouldn't be correct. C would defeat the meal plan's purpose which is to make your life easier and more convenient. D doesn't make sense, making too much food in case a guest dropped by would contribute to food waste because they may not show up. Instead, make a plan with the expectant (not unexpected) guest and incorporate into the meal plan. Finally, we have A. Using things that we already have can reduce food waste as you are using the last in, first out method which makes logical sense. So to conclude, the answer should be A.
