The assumption of a variance of zero is not appropriate for the error term in a regression model. This would imply that there is no variability in the dependent variable, which is not likely to be the case in a real-world situation. The other assumptions listed (constant variance, independence, normality, and mean of zero) are all commonly made about the error term in a regression model.
