The position vectors of $A$ and $B$ are $(\hat{i}+\hat{j}+\hat{k})$ and $(\frac{1}{3} \hat{j}+\frac{1}{3} \hat{k})$. If $B$ divides the line segment $AC$ in the ratio $2:1$,then the position vector of $C$ is

  • A
    $(\frac{1}{2}, 0, 0)$
  • B
    $(0, \frac{1}{3}, 0)$
  • C
    $(\frac{-1}{2}, \frac{-1}{2}, 0)$
  • D
    $(\frac{-1}{2}, 0, 0)$
