    Which of the following represents the Lewis structure of \[{{N}_{2}}\] molecule?

    A)  \[{}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}\text{N}\equiv \text{N}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}\]                              

    B)  \[\overset{\times \,\,\,\times }{\mathop{{}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}\text{N}}}\,\equiv \overset{\times \,\,\,\,\times }{\mathop{\text{N}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}}}\,\]

    C)  \[\overset{\times \,\,\,\times }{\mathop{{}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}\text{N}_{\times }^{\times }}}\,\,-\,\,\underset{\times \,\,\,\,\times }{\mathop{\overset{\times \,\,\,\,\times }{\mathop{\text{N}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}}}\,}}\,\]                       

    D)  \[\underset{\times \,\,\,\times }{\mathop{\overset{\times \,\,\,\times }{\mathop{{}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}\text{N}}}\,}}\,=\underset{\times \,\,\,\,\times }{\mathop{\overset{\times \,\,\,\,\times }{\mathop{\text{N}_{\text{ }\!\!\times\!\!\text{ }}^{\text{ }\!\!\times\!\!\text{ }}}}\,}}\,\]
