In a solid `AB` having the `NaCl` structure, A atom occupies 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

In a solid AB having NaCl structure 'A' atoms occupy the corners & face centre of the cubic unit cell. If all the face centered atoms along one of the axes are removed, then the resultant stoichiomery of the solid is

In a solid 'AB' having rock salt arrangement ( NaCl structure), 'A' atoms occupy the corners and face center of the cubic unit cell. 'B' atoms occupies all octahedral voids of the unit cell. If all the face - centered atoms along one of the axes are removed, then the resultant stoichiometry of the solid is

In a solid AB of NaCl structure, A atoms occupy the corner of the cubic unit cell. If all the corner atoms are removed then the formula of the unit cell will be
