Scatterplot B shows a clear linear association.

Reason: in B the y-values increase steadily as x increases and the points lie very close to a straight line (positive linear trend). (If you compute Pearson r for B you get about 0.995, confirming a very strong positive linear relationship.) The other sets show more scatter, clusters, or outliers that break any clear straight-line pattern.
