正解:C
The maturity stage is commonly characterized by market saturation, slower growth, intense competition, and increased product variation as organizations attempt to differentiate offerings and defend market share. Firms may create multiple models, packages, features, or customer-specific versions to appeal to different segments.
During introduction, the product category is still new and may have limited market acceptance. During growth, sales expand rapidly and competitors enter, but product variation is still developing. During decline, organizations usually reduce investment, simplify offerings, control costs, or exit unprofitable segments.
Internal auditors reviewing strategy should understand industry life-cycle stages because they affect pricing, inventory risk, marketing spend, innovation, and capacity planning. Therefore, Option C is correct.
