A solid has three types of atoms, such as \( X, Y \) and \( Z \).
P ' \( \mathrm{X} \) ' forms a FCC lattice with ' \( \mathrm{Y} \) ' atoms occupying all

W the tetrahedral voids and ' \( Z \) ' atoms occupying half the octahedral voids. The simplest formula of solid is
(1) \( \mathrm{X}_{2} \mathrm{Y}_{4} \mathrm{Z} \)
(2) \( \mathrm{XY}_{2} \mathrm{Z}_{4} \)
(3) \( \mathrm{X}_{4} \mathrm{Y}_{2} \mathrm{Z} \)
(4) \( \mathrm{X}_{4} \mathrm{YZ}_{2} \)
