`NaCl` shows Schottky defects and `AgCl` shows Frenkel defects. Their electrical conductivity is due to the

Options

A. Motion of electrons and not the motion of ions
B. Motion of ions and not the motion of electrons
C. Lower coordination number of `NaCl`
D. Higer coordination number of `AgCl`

Answer

B

Explanation

Because in both types of defects, the electrical conductivity is due to the movement of ions is the one direction aned movement of hole to other side.
