Conflict is happens when either one of the individuals have misunderstanding or are reaching over the same goal. The possible advices one can give to people in conflict are (1) talk things out, (2) listen to the side of the other, (3) be open-minded, (4) when explaining, explain it well, (5) face your responsibilities whether good or bad and (6) do not include people who are not part of the conflict, keep it among yourselves.
In a way, all of the options are correct: but most of them are not very explicit and too general. For example, a formal scientific study will as a result provide some insight into the topic: but this is not the direct goal of the study.
The best answer is that formal, scientific studies have the aim of testing the hypothesis- this is the correct answer.
