Many large corporations in the u. s. have started campaigns to "go green" and decrease the amount of pollution and waste products that they release into the environment. similarly, many companies are labeling their products as "environment-friendly" or "green" without scientifically explaining why their product is better for the environment than a competing product. this type of product labeling a. should be critically evaluated by consumers based on scientific evidence. b. should be critically evaluated based on the company's promotional packaging and presentation. c. is always accurate because companies would never try to deceive consumers. d. is always false and does not need to be evaluated by consumers.

The correct answer will be option-A.

Explanation:

The "environment-friendly or green" labels on the products sold in the U.S or in other countries indicates that the product is not harmful to the environment.

Although they put a label on the products but they do not provide information on why the products are environment-friendly. This condition forces the consumers to become skeptical to find the reasons.

The consumers, therefore, must critically evaluate the scientific data related to the products about how and why the product is environment-friendly.

Thus, option-A is the correct answer.
