The correct answer is C because customer feedback is qualitative, as it consists of textual information that reflects opinions. Classifying feedback into "Positive" and "Negative" represents categorical analysis, as these are distinct groups or classes. Option A : Quantitative data deals with numerical values, which is not applicable here. Option B : Predictive analysis forecasts future trends, while the task involves classification. Option D : Inferential analysis derives conclusions from sample data, not directly relevant here. Option E : Continuous data represents values on a continuum, such as time or temperature, not applicable to feedback categories.
