Answer:
The correct answer will be option other scientists repeated the experiment.
Explanation:
Ernst Rutherford is also known as "Father of nuclear physics" known for his planetary model of atom called "Rutherford model of the atom". He proposed and demonstrated the model in 1911 explaining that atom carries a small charged nucleus in the center which is surrounded by the tiny electrons.
The Rutherford's atomic model was accepted by the scientific community at that time because of the probable reason that his results were based on experiments which were also supported by the experiments of other scientists who repeated the experiments to check the accuracy and feasibility of the model. His experiments were repeated by a famous scientist and his student James Chadwick who discovered neutrons.
Thus, option other scientists repeated the experiment is the correct answer.
