    C)  \[2{{p}_{y}}\]and\[2{{p}_{y}}\]      

    D)  1s and 2s

    Correct Answer: C

    Solution :

     \[2{{p}_{y}}\]and\[2{{p}_{y}}\]will not form a\[\sigma -\]bond because on taking x-axis as internuclear axis\[2{{p}_{y}}\]and\[2{{p}_{y}}\]orbitals overlap sideway (lateral overlapping) resulting in the formation of a \[\pi -\]bond.
