• B. Markup
• C. Penetration Price
• D. Product Life Cycle

Answer: (D)

This item tests your understanding of a product's life cycle in the market. Products typically move through four phases—introduction, growth, maturity, and decline—with each stage showing different sales patterns and suggesting different marketing actions. The term that describes this progression and guides strategy across time is the Product Life Cycle. In the introduction phase, sales are slow and costs are high as you build awareness and distribution. In growth, sales accelerate and profits begin to rise as economies of scale kick in and competition increases. During maturity, sales peak and growth slows, often bringing intensified competition and a focus on differentiation, retention, and efficiency. In the decline phase, sales fall as the product loses relevance or is replaced by newer options, prompting decisions about harvesting, discontinuing, or reinventing the offering. The other options refer to pricing tactics rather than the overall trajectory of a product’s market life, so they don’t describe the four-stage progression.
