Letâ€™s see the K-Means algorithm in action using a visualisation tool. This tool can be found on naftaliharris.com. You can go to this link after watching the video below and play around with the different options available to get an intuitive feel of the K-Means algorithm.

Upon trying the different options, you may have noticed that the final clusters that you obtain vary depending on many factors, such as choice of the initial cluster centres and the value of K, i.e. the number of clusters that you want. You will understand these factors and other practical considerations while using the K-means algorithm in more detail in the next segment.

Now look at the given image and answer the question that follows:
