As we learnt in 

sp3 hybridisation -

when one s - and three p - orbital belonging to the same shell of an atom mix together to form four new equivalent orbitals is called sp3 orbital.

- wherein

Shape Tetrahedral 

 

 

 

 

NH3 and BF-14 both are sp3 hybridised and the expected bond angle of both is 109.28


Option 1)

NH_{3},\left ( BF_{4} \right )^{-1}

This solution is correct 

Option 2)

\left ( NH_{4}\left \right )^{+} ,BF_{3}

This solution is incorrect 

Option 3)

NH_{3}, BF_{3}

This solution is incorrect 

Option 4)

\left ( NH_{2}\left \right )^{-1} ,BF_{3}

This solution is incorrect
