Final answer:
The last stage in the hierarchy of effects model is 'C. Adoption', where individuals fully accept and begin using a product or service. It follows the stages of awareness, knowledge, liking, preference, and conviction, aiming towards brand loyalty and repurchase.
Step-by-step explanation:
The last stage in the hierarchy of effects is C. Adoption. The hierarchy of effects is a model that outlines the stages an individual goes through during the process of accepting a new idea or purchasing a product. It typically starts with awareness, building up through knowledge, liking, preference, conviction, and culminates in adoption. Adoption refers to the stage where an individual fully accepts the idea, product, or service and starts using it.
This model is important for understanding consumer behavior, guiding marketing strategies to convert potential customers into actual buyers. The ultimate goal is not just the initial purchase but leading to brand loyalty and repurchase. Repurchase indicates a long-term commitment to a product or brand, which is desired but is not technically the final stage of the classic hierarchy of effects model.
