Is D correct bc of the first sentence, "Most fad diets prescribe a single narrow range of nutrients for everyone." and ..."dietary needs vary from person to person." Here are my thoughts: After seeing the correct answer, I am thinking that bc this is a must be true question, answer D restates the first sentence by saying that most fad diets fail to satisfy the dietary needs of some people, which means that at least one person's dietary needs have not been satisfied bc the needs vary from person to person and the fad diet is prescribing a narrow range of nutrients. Is my line of thinking correct here? If not, please help me to better understand why D is correct. Thanks for the help!
