Aseries of experiments, which are repeated over and over, seem to suggest that a scientific theory is incorrect. what does this most likely mean?

a. the experiments were faulty.
b. the scientist was manipulating the results.
c. the theory must be revised.
d. the results should be modified to agree with the theory.

The correct answer is option C. The theory must be revised.

The theory is the scientific explanation of a phenomenon, which explains the working and its causes. The experiments performed to give a theory must be replicatable and must produce the same result all the time. In case, the experiment according to the theory produces different result many times when performed by different scientists, then there must be some fault in the theory, then it need to be revised.
