Answer:
C). Life stage
Step-by-step explanation:
Life stage marketing is characterized as the kind of marketing in which the significant products or services are offered on the basis of their stages of life. As people go through various stages or phases of life, their product preferences, purchasing decisions, shopping attitudes vary.
Therefore, the companies adopt life stage marketing to promote products directly to the target audience. For example, Madeline must adopt 'life-stage marketing' technique as diabetes is usually found in middle-aged or old-age people due to body's inability to use the insulin properly. Thus, this would allow Madeline to get the desired response by targetting such people directly by promoting her product before them. Thus, option C is the correct answer.
