    B) \[NO_{2}^{-}\]and \[N{{H}_{3}}\]

    C) \[B{{F}_{3}}\] and\[NO_{2}^{-}\]      

    D)  \[NH_{2}^{-}\]and \[{{H}_{2}}O\]

    Correct Answer: C

    Solution :

     \[\text{B}{{\text{F}}_{\text{3}}}\]and \[NO_{2}^{-}\] are \[s{{p}^{2}}\]hybridised while \[NH_{2}^{-},N{{H}_{3}}\]and \[{{H}_{2}}O\]are \[s{{p}^{3}}\]hybridised.
