Which of the following analysis techniques is an unsupervised data mining process?

[Reference:The CompTIA Data+ Certification Exam Objectives list clustering as a key unsupervised data mining technique., partners.comptia.org, Option B:Descriptive, Rationale:Descriptive analysis summarizes or describes the main features of a dataset, often through statistical measures or visualizations. While it provides insights into the data, it is not a data mining process but rather a preliminary step in data analysis., Option C:Regression, Rationale:Regression analysis is a supervised learning technique used to model and analyze the relationships between variables. It requires labeled data to predict outcomes and is not considered an unsupervised process., Option D:Predictive, Rationale:Predictive analysis involves using historical data to make predictions aboutfuture events. It often employs supervised learning techniques and relies on labeled datasets to train models., , ]
