Rutherford’s atomic model has the following features: -
i. There is a positively charged centre in an atom called the nucleus. Nearly all the mass
of an atom resides inside the nucleus.
ii. The electrons revolve around the nucleus in well-defined orbits which can be
compared to solar system.
iii. The size of the nucleus is very small as compared to the size of an atom.
Hence, statement I and iii are correct t.
So, the correct option is A.
