If we do know X , our measure of error is

The standard error of estimate is used to measure the difference between the observed values of Y and the predicted values of Y. It tells us how much variation there is between the actual and predicted values of Y, given that we know the value of X. The other options are measures of variability, but do not directly relate to the prediction error when X is known.
