Answer»

Correct option is (b) polymeric hydride

For explanation I would SAY: Polymeric hydrides are formed by elements having ELECTRONEGATIVITY in the range of 1.4 to 2.0. Examples of polymeric hydrides are (BEH2)n, (AlH3)n etc. They are joined to each other through HYDROGEN bonding in order to FORM a larger unit.
