The correct answer is d) Research design.
Research design is the step in the marketing research process that involves setting specific, measurable research objectives. This step is important because it helps guide the entire research process and ensures that the data collected will be relevant and useful in answering the research questions.
For example, if a company wants to determine the effectiveness of a new advertising campaign, they may set research objectives such as assessing brand awareness among the target audience or measuring the impact of the campaign on sales.
