Answer:
C) competition
Step-by-step explanation:
ACE's new computer is in the introduction stage of the product life cycle. It is a very new and different product and therefore ACE can charge a high price until the growth stage begins. During the growth stage, the product's demand will increase and it will become a normal available product, that will attract several competitors into the market. Competitors might introduce newer versions of the product which are slightly different, but specially the price will be a decisive factor. As more competitors enter the market, the price will fall.
