For two given vectors $\bar{a}$ and $\bar{b}$,if the vectors $\overline{A}$ and $\overline{B}$ are such that $\overline{A}+\overline{B}=\bar{a}$,$\overline{A} \times \overline{B}=\bar{b}$,and $\overline{A} \cdot \bar{a}=1$,then $\overline{A}=$

  • A
    $\frac{(\bar{a} \times \bar{b})+\bar{a}}{\bar{a}^2}$
  • B
    $\frac{(\bar{b} \times \bar{a})+\bar{a}}{\bar{a}^2}$
  • C
    $\frac{\bar{a}\left(\bar{a}^2-1\right)+(\bar{b} \times \bar{a})}{\bar{a}^2}$
  • D
    $\frac{(\bar{a} \times \bar{b})+\bar{b}}{\bar{b}^2}$
