Answer:
The correct option is 'develop an experiment to test her hypothesis and produce data'
Step-by-step explanation:
The scientific method of research starts with an observation. A question is generated by the observation seen. To answer the question, a hypothesis is made which is a tentative statement that can be proved right or wrong. To test the hypothesis, experiments are performed and results are interpreted. Then conclusions are made depending on the results.
Hence, after the hypothesis the next step that Dr. Jones should take is to perform experiments.
