Answer Key : (b) -

  Actinodes                                                Oxidation state  shown(Np and Pu)

     Th                                                                                            +4

      Ac                                                                                            +3

      Pu                                                                              +3, +4, +5, +6, +7

      Np                                                                              +3, +4, +5, +6, +7

      Bk                                                                                            +3, +4

      Cm                                                                                            +3, +4

       Lr                                                                                                  +3

∴  Maximum oxidation state is shown by the (Np and Pu)
