The product life cycle stage that is defined as "growth" is marked by

a. selling through warehouse stores, discount outlets, online clearance sites, and other methods to clear inventory and deplete all stock at the lowest prices as a product is discontinued.

b. adoption by the late majority and intense competition for market share among many firms.

c. greater segmentation with varied consumer preferences as sales increase, as well as the dramatic rise in profitability for the firm, and a significant need to keep up with demand.

d. initial losses due to high start-up costs for the firm and low levels of sales revenue as the product is introduced to the public.
