When a biologist in a laboratory reports a new discovery based on experimental results, biologists in other laboratories should be able to a. repeat the experiment with a different variable and obtain the same results. b. perform the same experiment and obtain different results. c. repeat the same experiment and obtain the same results. d. perform the same experiment under different experimental conditions and obtain the same results.

C.repeat the same experiment and obtain the same results.

Explanation:

In scientific research an experimenter should firstly follow the literature review  of the past scientific studies so as to attain the knowledge about the scientific design, methodology and results and conclusions. The experimenter should consider these parameters until the research process ends.

According to the given situation, C.repeat the same experiment and obtain the same results. is the correct option because of the fact that the reliability of the new discovery could be checked by this process by application of similar control experimental conditions. If similar results appear than it will prove that the new discovery was valid.
