Right answer is (b) ionic hydrides

For explanation: Ionic hydrides are formed by elements of group 1 and 2 except beryllium and magnesium, by heating them in hydrogen. They are white colourless crystalline solid having a high melting point and boiling point and they are easily decomposed by water, carbon dioxide or Sulphur dioxide.
