NEETPREP2019: See in NaCl. Na occupies Octahedral Voids and Cl occupies CCP arrangement. And the question says AB follows NaCl struc. so one atom will have Octahedral Voids and other CCP. Here since A occupies corners that means it will also occupy face centres and when one axis is removed two face centres will be removed so A= 1/8*8+1/2*4=3 and B will have Octahedral Voids so B=1/4*12+1*1=4. So it is A3B4
