Which statement best describes the product life cycle stages and their marketing implications?

• A. Intro, Rise, Maturity, Fade
• B. Introduction, Growth, Maturity, Decline; different strategies by stage
• C. Launch, Expansion, Maturity, End
• D. Introduction, Growth, Maturity, Decline; each stage requires different pricing, promotion, and distribution strategies.

Answer: (D)

The idea being tested is that a product’s marketing needs change as it moves through the four stages of the life cycle, with specific actions tied to each stage. The four stages are Introduction, Growth, Maturity, and Decline, and each one calls for different pricing, promotion, and distribution strategies to maximize success. At introduction, the goal is to build awareness and trial, often with strong promotional support and distribution setup. In growth, demand expands, so the focus shifts to widening distribution and staying competitively priced to capture the expanding market. During maturity, the market is crowded, so differentiation, selective promotions, and careful pricing help defend share while maintaining margins. In decline, sales drop, so strategies tilt toward cost control, concentrating distribution, and choosing whether to harvest, reposition, or divest. This statement is best because it names the four stages and explicitly links marketing implications—pricing, promotion, and distribution—to each stage. Other options either use nonstandard stage names or are too vague about the concrete marketing actions tied to the stages.
