A) Association rule mining

B) Discriminant analysis

C) Cluster analysis

D) Logistic regression

The correct answer is option C) Cluster analysis .

Step-by-step explanation:

We denominate Cluster analysis to the act of matching up a group of things in such a way that each thing that makes up this group (cluster) has things in common between one and other, in some way.

This is widely used in the analysis of statistical data and in marketing.
