The cluster analysis refer to an activity in which there is a group of objectives set that shows the objects in the similar group that we called as a cluster

Here in the given situation, it is mentioned that the use of descriptor variables is used for cluster analysis in order to make a difference in sub samples

So here the description step is used in cluster analysis

Therefore the third option is correct
