Based on the typical behavior of residual plots, if the residual plot shows a clear pattern, it suggests that the linear model is not an appropriate fit for the data. Therefore, the correct response would be:
The given residual plot clearly has a pattern. Therefore, a linear model is not reliable and will not provide accurate predictions for the original data.
If the residual plot is randomly and equally distributed around the line where residual = 0, it indicates that the linear model is a good fit. However, since the question specifies that there is a pattern, it confirms the unreliability of the linear model.
