Image with description A scatterplot is shown on a first quadrant coordinate plane. There are 8 data points that form a straight line.

Explanation

An outlier is a data point that lies far from the overall pattern of the other points. In choice B, nine points are clustered near the bottom left, while one point is far away near the top right. The points in the other choices are clustered together or follow a straight-line pattern without a clearly separated point.
