Answer: C. Conducting the experiment again.
Step-by-step explanation:
The new research and innovation in the field of science has become common with the improvement in technology and expansion of the scientific knowledge. The validity and reliability of the new research can be determined by the peer review and finding the errors, by following the same research methodology that has been used in the new research and comparing the results.
Conducting the experiment again is the correct option. As this involves the implementation of the same methodology used for the purpose of the experiment. If the data of the experiment matches with that of the new experiment than the data can be considered as valid and real.
