In the study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. but, all researchers have arrived at the same conclusion. what does this say about the conclusion? a.) it is well supported. b.) it is weakly supported. c.) it is inconclusive. d.) it is refuted.

The correct answer is option A

The study of cancer shows that the researchers have used many different environmental conditions and along with this they also used different types of cells for their experiment.

At the end all the researchers have agreed on the same conclusion which means the data was well supported.

If there could have been any mistake in the experiment then the conclusion would have been different for different researchers.
