According to Rutherford’s model, positive charge is:
Concentrated at the centre
Rutherford's alpha-particle scattering experiment showed that most of the mass and all the positive charge of an atom is concentrated in a tiny, dense region at the centre, called the nucleus.
Hence, the correct answer is Concentrated at the centre (B).
