Answer:
C) Hypotheses suggest new questions for further investigations.
Explanation:
The hypothesis is your prediction in an experiment- it's a matter of your own logic and personal opinion made before conducting.
It cannot be D, since they don't always match the conclusion.
Regarding B, the hypothesis doesn't give details about the data, since it is written before collecting data.
Hypotheses can definitely help identify variables, but that's not the point of writing one.
The answer is C, as the hypothesis helps open up what your prediction for the experiment is.
