Which model has the lowest expected test error?

You are choosing a forecasting model. The expected squared error of a prediction splits into three parts: $\text{squared bias} + \text{variance} + \text{irreducible noise}$. The noise is 4 for every model. The models are:

• Model A: squared bias 9, variance 1
• Model B: squared bias 1, variance 6
• Model C: squared bias 0, variance 12

Which model has the lowest expected test error, and what is it?
