Explanation:

A correlation coefficient close to 1 means there is a strong positive linear relationship between the two variables, where data points lie very close to an upward-sloping straight line. Graph A has points tightly clustered along an upward trend line, showing this strong positive linear association. Graph B has more scattered points, and Graph C shows a weaker, less linear trend.
