In NaCl structure, Cl⁻ ions form a cubic close packed (CCP/FCC) arrangement, and Na⁺ ions occupy all octahedral voids.

Each Na⁺ ion has 6 nearest neighbors of Cl⁻ ions (coordination number = 6).

Na⁺ ions do not form a BCC lattice; they form an FCC arrangement.

Each Na⁺ ion has 12 next nearest neighbors (not 8).

Incorrect statements:

(b) Na⁺ ions make bcc lattice and (d) 8 next nearest neighbors
