HAC standard errors should be used because
 
  A) they are convenient simplifications of the heteroskedasticity-robust standard errors.
  B) conventional standard errors may result in misleading inference.
  C) they are easier to calculate than the heteroskedasticity-robust standard errors and yet still allow you to perform inference correctly.
  D) when there is a structural break, then conventional standard errors result in misleading inference.
