A) The sum of the error terms is a minimum, and the SSE is a maximum.
B) The sum of the error terms is zero, and the SSE is zero.
C) The sum of the error terms is zero, and the SSE will depend upon the significance level.
D) The sum of the error terms is zero, and the SSE is a minimum.
E) The sum of the error terms is always smaller than other lines, and the SSE is zero.
