One Key Feature of the Value of a Strong Brand

One key feature of the value of a strong brand is that

A) it can protect the firm from competition.
B) it no longer needs to be supported by advertising and promotion.
C) if it becomes a generic name, the brand is worth even more.
D) it cannot be successfully imitated by a retailer's own brand.
E) competitors will typically abandon a sector altogether rather than compete.
Strong brands protect the firm somewhat from competition because the brand differentiates the firm's products, making customers more loyal.
