    A) \[A{{l}_{2}}{{O}_{3}}\]

    B) \[S{{b}_{2}}{{O}_{3}}\]

    C) \[B{{i}_{2}}{{O}_{3}}\]

    D) \[Se{{O}_{2}}\]                   

    Correct Answer: C

    Solution :

    [c] In\[A{{l}_{2}}{{O}_{3}}\], \[S{{b}_{2}}{{O}_{3}}\], \[B{{i}_{2}}{{O}_{3}}\]and\[Se{{O}_{2}}\].\[B{{i}_{2}}{{O}_{3}}\]  is most basic oxide due to higher reactivity with acid \[B{{i}_{2}}{{O}_{3}}+6HCl~\to 2BiC{{l}_{3}}+3{{H}_{2}}O\]
