Choice "A" is correct. Big Box would use transaction marketing practices that emphasize a single sale with no further interaction necessarily required. Customers are attracted to low prices and will likely return based on price only.
Choice "b" is incorrect. Interaction-based relationship marketing says that sales further relationships, thereby driving more sales. Big Box's strategy is to move product through low prices, not to promote relationships.
Choice "d" is incorrect. Database marketing uses data as the foundation for identifying target markets. Big Box promotes low prices without targeting any specific database.
Choice "c" is incorrect. Network marketing is a form of referral and relationship marketing. Big Box focuses on low price transactions, not customer referrals and relationships.
