Answer:
B) To remain competitive, companies must be prepared to add to or adapt their product lines to satisfy customer desires.
Step-by-step explanation:
The fact that many consumers are complaining about the products that Marissa sold, means that her sales probably went down. When sales are down, any company is in big trouble.
In order to regain a competitive advantage, Marissa and other companies must be willing to offer the products or services that will satisfy their customers' needs.
About 100 years ago, companies sold what they produced and consumers' voices and needs were not important, but that was 100 years ago. Today, if you do not satisfy your consumers' needs and desires, you lose them immediately.
