An element exists in two crystallographic - modifications with FCC and BCC structures. The ratio of the densities of the FCC and BCC modifications in terms of the volumes of their unit cells $\left(\mathrm{V}_{\mathrm{FCC}}\right.$ and $\left.\mathrm{V}_{\mathrm{BCC}}\right)$ is
(a)$\mathrm{V}_{\mathrm{BCC}}: \mathrm{V}_{\mathrm{FCC}}$
(b)$\mathrm{V}_{\mathrm{BCC}}: 2 \mathrm{V}_{\mathrm{FCC}}$
(c)$2 \mathrm{V}_{\mathrm{BCC}}: \mathrm{V}_{\mathrm{FCC}}$
(d)$\mathrm{V}_{\mathrm{BCC}}: \sqrt{2} \mathrm{V}_{\mathrm{FCC}}$
