I think C) The omission of a relevant explanatory variable can also cause issues with autocorrelation or heteroskedasticity.

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

Using an inappropriate functional form? That's like trying to fit a square peg into a round hole. Rookie move.

The omission of a relevant explanatory variable is a classic cause of heteroskedasticity. Rookie mistake, really.

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!
