Which statement is true about the residual plot below ?

The option should be B, after we eliminated these other 3 options with reasons as below:

A - Without details data, if we see from the plot only, there is no way to confirm the residual is greater - equal - smaller than 0

C - There is always a good regression model for any data

D - This is Heteroscedasticity case. Hence, the linear model is not a good approach.

Hope this helps!
