    A) H-H

    How can this be possible ? the Bond lenght Depends on the Electronegativity ? isn't it ?
    And i guess they were asking about Shortest Bond lenght not the Largest !
    H-Br was the one i reccon ?

    If that was the case then it would be H-N not H-Br as nitrogen has greater electronegativity

    a) CO
    b) H2S

    Yea it was H-H

    The question was asking for the shortest covalent bond length. HBr is an ionic bond.
