Which term refers to the stages a product goes through from development to decline?

• A. Product life cycle
• B. Product line
• C. Brand lifecycle
• D. Life-span curve

Answer: (A)

Think about how a product moves from an idea through launch and into its later years in the market. The progression that names this whole sequence is the Product life cycle. It describes the stages a product goes through—development, introduction, growth, maturity, and decline—and helps marketers plan what to do at each point, like how to allocate resources, set pricing, and tailor promotions. The other terms describe different things: a product line is a group of related products a company sells, a brand lifecycle refers to the overall journey of a brand rather than a single product’s stages, and life-span curve isn’t the standard label for this concept. So the best fit for stages from development to decline is the Product life cycle.
