    B) krypton

    Explanation:

    Electron configuration of Br: [Ar] 3d10 4s2 4p5

    Since we have the bromide ion with a negative charge, Br's atom acquired an electron and therefore another electron is added to the electronic configuration.

    Electron configuration of Br-: [Ar] 3d10 4s2 4p6

    And now this electronic configuration coincides with that of Krypton as we see below:

    Electron configuration of Kr: [Ar] 3d10 4s2 4p6
