I agree with Erick, D) makes more sense because it can lead to misspecification of the model.

Wait, isn't autocorrelation and heteroskedasticity like the regression model's way of saying 'I don't feel so good'?

A structural break in the dependent variable? Sounds like a plot twist in a crime novel, not a regression issue!
