Based on These Regression Results, in Your Judgment Which Statement

Based on these regression results, in your judgment which statement is most nearly correct (Y = highway miles per gallon in 91 cars) ? $$\begin{array}{l}\begin{array} { r r r r } \mathrm { R } ^ { 2 } & 0.499 & & \\\text { Adjusted } \mathrm { R } ^ { 2 } & 0.444 & \mathrm { n } & 91 \\\mathrm { R } & 0.707 & \mathrm { k } & 9\end{array}\\\begin{array} { l l l } \text { Std. Error } & 4.019 & \text { Dep. Var. HwyMPG }\end{array}\\\begin{array} { l r r r r r } \hline \text { Source } & \text { SS } & d f & M S & F & p \text {-value } \\\hline \text { Regression } & 1,305.7251 & 9 & 145.0806 & 8.98 & .0000 \\\text { Residual } & 1,308.3848 & 81 & 16.1529 & & \\\hline \text { Total } & 2,614.1099 & 90 & & & \\\hline\end{array}\end{array}$$

A) The number of predictors is rather small.
B) Some predictors are not contributing much.
