The correct answer is D because there is one area that is a cluster (bundle of dots in one area) and one outlier (away from all the other points; irrelevant).
We are given the following information in the question:
We are given a scatter plot.
Sometimes the data points in a scatter plot form distinct groups. These groups are called clusters. A cluster is formed when several data points lie in a small interval.
An outlier is defined as a data point that can be differentiated from the rest of the data. It is an observation that lies an abnormal distance from other values in a random sample from a population.
When observed, the given scatter plot has one cluster and one outlier.
