Ok i just took this exam the above answer was wrong the real answer should be: More investigations must be completed.

The correct answer is option D, More investigations need to be completed

Explanation:

When a scientific investigation produces evidence that does not support the hypothesis, some lacuna must have occurred in the research process. Therefore it is the duty of the researcher to look for the missed out things and lead the research in the right direction. The researcher may not be able to find the exact issue in the research, thus his first step would be to find the stage at which the fault has occurred and then  rectify it. After that the researcher must do further detailed investigation to collect the evidence that support the hypothesis and thus complete the investigation.

the answer would be knowledge about cars!
