You have fit a k-means algorithm with six clusters. The results are visualized below. Based on the plot, which statement is true?

 

There is overlap between some clusters, which indicates there is no significant difference between some clusters and fewer clusters should be created.

 

There is good separation between the clusters. There is no need to try to fit a different number of clusters.

 

There is significant overlap between many of the clusters, but the added complexity is providing adequate separation.
