    B)        \[{{O}_{2}}\]      

    C) \[{{N}_{2}}\]               

    D)        \[{{N}_{2}}O\]

    Correct Answer: B

    Solution :

    \[Pb{{O}_{2}}\] is a powerful oxidizing agent and liberate \[{{O}_{2}}\] when treated with acids. \[2Pb{{O}_{2}}+4HN{{O}_{3}}\xrightarrow{{}}2Pb{{(N{{O}_{3}})}_{2}}+2{{H}_{2}}O+{{O}_{2}}\uparrow \]
