Step-by-step explanation:
The answer to the student's question is c. product life cycle. The product life cycle is a well-established business concept that delineates the stages a product goes through from when it first enters the market until its eventual decline and exit from the market.

Understanding the product life cycle is important for businesses as it helps them strategize and make decisions about product development, pricing, marketing, and eventual discontinuation. This concept is applicable not only in technology and sales but also in cultural innovations, consumption patterns, and brand development strategies.
