Answer:
D.) Nutrition Facts labels
Step-by-step explanation:
A.) is incorrect because these types of books are often misleading. If anything, these books likely contain harmful dieting techniques. They are not bound by any law to contain accurate information.
B.) is incorrect because advertisements only show the most appealing information about a product. Therefore, they are likely to leave out important, less attractive, and potential risky information pertaining to their product.
C.) is incorrect because it is very easy to get nutrition facts incorrect. You cannot be sure on the source of their information or if they forgot important facts.
D.) is correct because nutrition fact labels are required by law to include accurate information describing a product. They are not allowed to skew numbers to make them more appealing or leave out potential side effects.
