What are the stages in a product's life cycle?

• A. Introductory stage, growth stage, maturity stage, and decline stage.
• B. Introductory and growth only.
• C. Growth, plateau, decline.
• D. Innovation, adoption, saturation, decline.

Answer: (A)

The product life cycle is described by four distinct stages: introduction, growth, maturity, and decline. Each stage reflects typical patterns in sales, profits, and the marketing approach required to support the product through that phase.

In the introductory stage, awareness is low, sales grow slowly, and costs are high as initial investment and learning occur. The growth stage brings rapidly rising sales and increasing profits as the product gains traction and market acceptance. During maturity, sales peak and then level off; competition tightens, margins tighten, and the focus shifts to differentiation, efficiency, and extending the product’s relevance. Finally, in the decline stage, demand wanes, profits shrink, and decisions focus on harvesting, repositioning, or phasing out the product.

The option listing these four stages—introductory, growth, maturity, and decline—best captures the standard progression of a product’s life cycle. Other choices mix in stages like adoption, saturation, or innovation, which describe related concepts (such as how customers adopt a new product) rather than the product’s life cycle itself, or omit stages that are essential to the traditional model.
