A Three-Variable Multiple Regression Establishes an Estimated Multiple Regression Equation

A three-variable multiple regression establishes an estimated multiple regression equation. Which of the following is a property of that equation?

A) All the estimates derived from it fall on a surface that is called the regression plane.
B) All the estimates derived from it fall on a surface that is called the regression plane, which is positioned among the sample points in such a way as to minimize the sum of the square horizontal deviations between these sample points and their associated estimates.
C) All the estimates derived from it fall on a surface that is called the regression plane, which is positioned among the sample points in such a way as to minimize the sum of the squared horizontal deviations between these sample points and their associated estimates, all of which lie on this plane.
