What is missing from JC's scientific investigation is AN HYPOTHESIS BASED ON RESEARCH THAT CAN BE TESTED. The correct option is C. In order to determine the relationship between two parameters in a research one has to formulate an hypothesis which can be tested out physically to validate its authenticity. This will give other scientists the opportunity to reproduce the research in any part of the world in order to verify its results.
