Answer:
C) need recognition
Explanation:
The need recognition stage is usually referred to as the problem identification stage. This is the first stage of the consumer decision making process, since the customer realizes that she has an unsatisfied need and is willing to acquire a good or service that will satisfy it.
Usually consumers identify problems or needs through internal factors, e.g. someone is hungry and needs food, or through external factors like advertisement, e.g. I just saw an ad about a new software that can make help me finish my accounting tasks faster.
