$1\mathrm{.}1\mathrm{.}1.(5$ points$)$ Consider the $2$ datasets A and B $.$ Each dataset is classified into $\backslash ($ k $\backslash )$ clusters, with centers marked $\backslash ($ X $\backslash )$ and cluster membership represented by different colors in the figure. For each dataset, exactly one clustering was generated by $\backslash ($ k $\backslash )-$means with Euclidean distance. Select the image with clusters generated by $\backslash ($ k $\backslash )-$means.
