Several companies are introducing "green" practices, such as reducing waste and energy consumption, to improve their public image. However, implementing these practices often leads to an increase in operational costs. Therefore, these companies are unlikely to gain a competitive advantage solely by implementing environmentally friendly practices.
Which of the following, if true, most strengthens the argument?
(A) Consumers are more likely to buy products from companies with strong environmental records, even if those products are more expensive.
(B) Government regulations require companies to implement certain environmentally friendly practices, thereby increasing their costs.
(C) Companies that adopt environmentally friendly practices generally do so in response to consumer demand.
(D) The costs of implementing environmentally friendly practices are often offset by long-term savings in energy and waste disposal costs.
(E) Most consumers are not aware of the environmental practices of the companies from which they purchase goods.
