Among CaH_(2),NH_(3), and B_(2)H_(6) which are covalent hydrides?

Dihydrogen, under certain reaction conditions, combines with almost all elements, except noble gases, to form binary compounds, called hydrides. If 'E' is the symbol of an element, then hydride can be expressed as EH_x (e.g.HgH_2) or E H_x (e.g. B_2H_6) . The hydrides are classified into three categories : ionic, covalent and metalic Among CaH_2, NH_3, NaH and B_2H_6 , which are covalent hybrides ?
