Answer:
The correct answer is C: More investigations need to be completed.
Step-by-step explanation:
If a scientific investigation has invalid evidence, it is not just instantly called history and tossed away. But it can not be valid either. In order to get your valid answer for a scientific investigation, you MUST gather CORRECT and VALID information. The whole point of having an experiment is to TRY and TRY again until you are certain the answer you have is VALID. If you need a screenshot that it is true, then I will have it posted below. I was taking the same quiz and instantly knew the CORRECT ANSWER. You CANNOT just call your failure a law, call the failed theory correct, or just call it invalid! As stated in the scientific method I believe; you must repeat your experiment over and over until you have direct proof.
