Answer:
C). Should there be limits on what scientists can clone?
Step-by-step explanation:
Research questions are crucial not only to direct the research but also to narrow the topic and focus on a specific topic that results in effective research. The formation of research questions is the germinal stage/phase of research that aids to specify the topic/concern as a too wide topic could be unmanageable. It aids to propose a question that needs to be answered efficiently throughout the research.
As per the given question, the best research question for a research report would be 'Should there be limits on what scientists can clone?' as this would provide direction to the research and form a productive argument to carry forward throughout the research and offer an effective research report. Thus, option C is the answer.
