A strong internationally recognized brand creates customer loyalty, trust, reputation, and perceived quality. New competitors must spend heavily on advertising, promotion, distribution support, customer education, and brand-building to overcome that loyalty. Therefore, the entrance barrier is increased marketing cost. A new competitor does not necessarily have to initiate a price war, although price competition may occur. Production costs are not automatically higher simply because an incumbent has a strong brand. Learning costs may exist in some industries, but they are not the primary barrier created by brand recognition. Internal auditors reviewing strategic risk should consider brand strength because it affects market entry risk, customer retention, intangible asset value, and competitive positioning. Therefore, Option C is correct.
