Solution

The correct option is A NH3 and B2H6
For covalent hydrides, H should bond with elements of electronegativity close to it.
NH3 is a covalent compound.
Na and Ca are highly electropositive.
Thus, B2H6 is also a covalent compound
(Remember that B is left of C which forms covalent bonds with H)
