duplicating the results of an experiment revising the original hypothesis developing a theory based on the data changing the experimental procedures
I gave my students this multiple choice question: Which process will most likely lead to the scientific acceptance of a hypothesis?

Only one answer is correct among these 4 choices:
- duplicating the results of an experiment
- revising the original hypothesis
- developing a theory based on the data
- changing the experimental procedures

Could you tell me which one is correct?
