Answer:
Letter a is correct. Private-label brand.
Explanation:
Private label brand occurs when a company manufactures and supplies a product to another company that only labels it with its brand.
This strategy is used by companies for a number of added benefits, such as increasing revenue streams and increasing the degree to which consumers perceive their brand. In addition to being a cheap strategy for the company, it pays the supplier for the product and not for the value of a brand added to a product. There is also greater control over the possibility of changing price, product and other variables that help gain competitive and economic advantages.
