Explanation:

Step1: Recall the characteristics of a normal quantile plot

A normal quantile plot (also known as a Q - Q plot) is used to assess if a data set comes from a normal distribution. If the data points lie approximately along a straight line, the data is likely from a normal distribution.

Step2: Analyze each option

• Option A: The points are not closely following a straight line.
• Option B: The points are closely clustered around a straight line, which is the characteristic of a normal quantile plot for data that is approximately normally distributed.
• Option C: The points are not following a straight - line pattern well.
• Option D: The points are not following a straight - line pattern well.

Answer:

B.
