A) Very close to 0
B) Very close to −1
C) Very close to .5
D) Very close to +1
E) Very close to positive infinity

The R2 statistic measures the proportion of the variation in the dependent variable that is explained by the independent variable(s). A value of 1 indicates a perfect fit, while a value of 0 indicates no relationship between the variables. Therefore, if the "goodness of fit" is nearly perfect, the value of R2 would be very close to +1.
