In a solid 'AB' having the \( \mathrm{NaCl} \) structure, 'A' atoms occupy the corners of the cubic unit cell. If all the face-centred atoms along one of the axes are removed, then the resultant stoichiometry of the solid is
(A) \( \mathrm{AB}_{2} \)
(B) \( \mathrm{A}_{2} \mathrm{~B} \)
(C) \( \mathrm{A}_{4} \mathrm{~B}_{3} \)
(D) \( \mathrm{A}_{3} \mathrm{~B}_{4} \)
