Answer 1

I would say Centroid-based clustering, because it is the most frequently occurred model thanks to its comparative simplicity. The model is aimed at classifying each object of the dataset to the particular cluster. The number of clusters (k) is chosen randomly, which is probably the greatest “weakness” of the method.
