MSR (Mean Square Regression) is the sum of squares explained by the regression model. It is equal to the regression sum of squares (SSR) divided by the regression degrees of freedom (dfR).

MSR = SSR / dfR

In the ANOVA table, we can see that SSR is equal to 400 and dfR is equal to 2. Therefore,

MSR = 400 / 2

MSR = 200

So the MSR value is 2000.

The correct answer is B.
