Question
Match the defects given in Column I with the statements in given Column II.
  Column I   Column II
(i)
Simple vacancy defect
(a)
Shown by non-ionic solids and increases density of the solid.
(ii)
Simple interstitial defect
(b)
Shown by ionic solids and decreases density of the solid.
(iii)
Frenkel defect
(c)
Shown by non ionic solids and density of the solid decreases.
(iv)
Schottky defect
(d)
Shown by ionic solids and density of the solid remains the same.
