An Arrhenius base increases the OH- ion concentration when added to water.  NaOH is such a base.  The others are not.

A Brønsted-Lowry base is one that can accept a proton.  I'm not convinced NH3 is such a base, but I'm not a chem geek.

NH3 is a Lewis base (donates a pair of electrons to a Lewis acid).  I question whether Br- is a Lewis base, but don't know for sure.
