The correct answer is D. Conducting effective market research
Explanation:
Surveys and focus groups are common research methods used by producers (people that create products) to collect information about customers. In the case of surveys, this method involves asking questions to a group of people to know their opinions and preferences; for example, a producer of clothes can use a survey to ask people about preferred materials. On the other hand, a focus group implies a small group of people discussing a common topic; for example, a producer of a cleaning product can use a focus group to know what customers think about the product.
These two strategies are used to conduct market research, this means the information obtained from surveys and focus groups is used to create plans and strategies to effectively advertise products or solve a problem related to this area. Thus, the purpose of using surveys and focus groups is "conducting effective market research".
