Best answer
Right choice is (b) metallic hydrides

The best explanation: The metallic interstitial hydrides’ composition varies with temperature and pressure, they are non-stoichiometric in nature and example for this is LaH2.76. These hydrides are formed when transition metals and rare Earth metals combine with hydrogen.
