Answer:
The correct answer is B. Be open to the idea that the hypothesis might be wrong.
Step-by-step explanation:
When conducting research and forming a hypothesis, historians should maintain an open mindset and be willing to consider alternative explanations or outcomes. They should not be biased towards confirming their hypothesis but rather approach the research process with a critical and objective perspective. Being open to the possibility of being wrong allows historians to explore different perspectives and interpretations, which contributes to the rigor and accuracy of historical analysis.
