The basic assumption of cluster analysis is that it is always possible to group data into well-defined homogeneous groups and the basic measurement of similarity is a valid measurement of proximity between objects. Additionally, there may be theoretical justification for structuring the objects into clusters, but this is not always necessary for cluster analysis to be performed. Therefore, the correct choice is E, which includes 2 and 3 as valid assumptions.
