Answer:
Option C
Step-by-step explanation:
Scientific claims should be questioned if they are based on a very small sample of evidence" or option C. If you do not have evidence to support your claim then your claim can not only be easily tested, but it can also be easily wrong. You should do your diligence to have all the evidence/data to support your claim even conducting experiments to get results and then having your peers repeat that experiment to get the same results.
It's not option A because, just because you don't agree with it, doesn't mean it's wrong. If you don't agree with a claim being made you should do your diligence to conduct your own experiments and gather together your own data to prove otherwise.
It's not option B because if you can't understand it, it doesn't mean it's wrong. You simply need to ask a peer to help you go through the claim being made to HELP you understand it.
It's not option D because just because it's new, doesn't mean it's false, it just means it's new. Again, you can do your own testing to these claims and gather data's to rather support or don't support the claims being made.
Your answer is option C.
Hope this helps.
