Q)

If $\overrightarrow d=x(\overrightarrow a \times\overrightarrow b)+y(\overrightarrow b\times\overrightarrow c)+z(\overrightarrow c\times\overrightarrow a)$ and $[\overrightarrow a\:\overrightarrow b\:\overrightarrow c]=\large\frac{1}{8}$, then $x+y+z=?$

$\begin{array}{1 1} (A)\frac{3}{8} [\overrightarrow a\:\overrightarrow b\:\overrightarrow c] \\ (B) 8(\overrightarrow a+\overrightarrow b+\overrightarrow c).\overrightarrow d \\ (C) \large\frac{3}{8}(\overrightarrow a+\overrightarrow b+\overrightarrow c).\overrightarrow d \\ (D) \large\frac{1}{8}(\overrightarrow a+\overrightarrow b+\overrightarrow c).\overrightarrow d \end{array} $
