Let $G$ be the specific gravity of soil solids. $w$ ' the water content in the soil sample, $\gamma_{w}$ the unit
weight of water, and $\gamma_{d}$ the dry unit weight of the soil. The equation for the zero air voids line in a compaction test plot is
(A) $\gamma_{d}=\frac{G \gamma_{w}}{1+G w^{\prime}}$
(B) $\gamma_{d}=\frac{G \gamma_{w}}{G_{11}}$
(C) $\gamma_{d}=\frac{G_{11}}{1+\gamma_{w}}$
(D) $\gamma_{d}=\frac{G_{11}}{1-\gamma_{w}}$
