Question

1. choose the best answer.

the ____ is a period of time over which a product is developed, sold, and eventually removed from the market.
product circle
product shift
product life cycle
product planning cycle

Explanation:

The question describes the period a product goes through from development to removal from the market. This is a core concept in marketing called the product life cycle, which includes stages like introduction, growth, maturity, and decline. The other options do not match this definition: "product circle" is not a standard term, "product shift" refers to changing product focus, and "product planning cycle" is about the planning phase only, not the entire lifespan.

Answer:

C. product life cycle
