Which of the following residual plots indicate a non-linear model? Click on the graph until the correct one appears.

A is indicating a non-linear model.

Step-by-step explanation:

I suppose these are residuals of a linear model, like OLS regression.

A linear model should result with residuals centered around 0 and normally distributed within any range.

In figure A, we see that the residuals have a trend with respect to d2, signing a possible non-linearity.
