JEE Advanced 2023 Chemistry question on States of Matter

Atoms of metals x, y, and z form face-centred cubic (fcc) unit cell of edge length $L_x$, body-centred cubic (bcc) unit cell of edge length $L_y$, and simple cubic unit cell of edge length $L_z$, respectively.

If $r_z = \dfrac{\sqrt{3}}{2}\, r_y$ ; $r_y = \dfrac{8}{\sqrt{3}}\, r_x$ ; $M_z = \dfrac{3}{2}\, M_y$ and $M_Z = 3M_x$, then the correct statement(s) is(are)

[Given: $M_x$, $M_y$, and $M_z$ are molar masses of metals x, y, and z, respectively. $r_x$, $r_y$, and $r_z$ are atomic radii of metals x, y, and z, respectively.]
