Answer : Option B) He could determine whether the hypothesis is based on repeated experiments.

Explanation : If the hypothesis is based on repeated experiments then it is a scientific theory. So, if Francis wants to find the hypothesis is theory or not he can simply perform experiments and get confirmed by the results of the experiments.

As a hypothesis can be defined as a rational explanation of a single event or phenomenon based upon what is observed during a particular experiment, but which has not yet been proved. Most of the hypotheses can be supported or refuted by experimentation or continued observation.

Whereas a scientific theory is more like a scientific law which is in mutual agreement with the the given hypothesis. One can perform experiments and compare the results with the theory and get confirmed.
