Final answer:
In the Decline phase of the product life cycle, marketers conduct little or no promotional activities to reduce expenses as the product's profitability diminishes.
Step-by-step explanation:
In the product life cycle, the phase where marketers engage in little or no promotional activities is D) Decline. During this phase, the product has already been established and may have become outdated, or the market is saturated, leading to a decrease in sales. Companies may reduce marketing expenses to minimize costs as the product's profitability declines.
Each phase of the product life cycle—Introduction, Growth, Maturity, and Decline—has different marketing strategies. In the Introduction phase, there is significant marketing to create awareness. The Growth phase involves aggressive advertising and promotions to capture market share. During the Maturity phase, marketing efforts are sustained to maintain market position. However, in the Decline phase, the focus shifts away from promotion toward cost management or product phase-out strategies.
