Answer:
D) the use of terms "light" and "natural" are allowed on labels only in the United States.
Explanation:
As the term "light" has a dictionary meaning of a very low in weight as compared to similar products in the market, is a very basic term to define the nature of product.
No labelling regulator has claimed that this kind of labelling is only allowed in the United States.
Further, the dictionary meaning of the word "natural" with respect to products shall mean, one that is not composed of high chemicals or transformation, but the major essence is extracted from the nature, i.e. from the environment.
Thus, the word natural can again be used by any country to label their product and in no manner is restricted to the United States.
