The assumption of the simple linear regression model is that the error term has a mean of zero for all values of x. If the error term increases as the value of x increases, this violates the assumption and suggests that there is a relationship between x and the error term, which should not exist in a simple linear regression model. A, B, and C are all assumptions that must be met in order for the simple regression model to be valid.
