What is the guiding principle behind all Amazon retail programs?

Amazon's core philosophy, deeply embedded in all its programs and operations, is "Start with the customer and work backwards." This principle means that every decision, product, and service development begins by identifying customer needs and then designing solutions to meet those needs. This customer-centric approach drives innovation and ensures that Amazon consistently delivers value to its users. The other options are incorrect because Amazon explicitly states that the customer, not the advertiser, product, or company itself, is the starting point for its backward-working methodology.
