A complex is composed of one chromium ion, three bromides and six water molecules. Upon addition of excess $\mathrm{AgNO}_{3}$, 1.0 g aqueous solution of the complex gave 0.94 g of AgBr. The molecular formula of the complex is (Atomic weight: $\mathrm{Cr}=52$, $\mathrm{Br}=80$, $\mathrm{Ag}=108$, $\mathrm{O}=16$ and $\mathrm{H}=1$)
(a) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Br}_{3}$
(b) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5} \mathrm{Br}\right] \mathrm{Br}_{2} \cdot \mathrm{H}_{2} \mathrm{O}$
(c) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{4} \mathrm{Br}_{2}\right] \mathrm{Br} \cdot 2 \mathrm{H}_{2} \mathrm{O}$
(d) $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{3} \mathrm{Br}_{3}\right] \cdot 3 \mathrm{H}_{2} \mathrm{O}$
