NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which `r_”Na”^+` and `r_”Cl”^-` are 95 and 181 pm respectively , where `Cl^-` is present at the lattice point of face centered cubic unit cell `Na^+` ions are located in void and those compounds which have same crystalline structure also have same coordination system in which `Na^+` and `Cl^-` ions are surrounded by certain number of opposite ions respectively. Under high pressure coordination number changes to 8 :8 type from 6 :6 type.

A. From NaCl to CsCl
B. From NaCl and ZnS
C. NaCl remains NaCl
D. It cause Shottky defect
