Verified Answer :

Answer: C. It provides information about what is already known about a particular research question.


Background research is a research which is done before designing a new research plan. This involves a review of complete history and nature of research problem with respect to the existing literature. Therefore, background research provides  already known information about a particular research.

The answer is C. When you design an experimental plan, the main thing is about the novelty of the research and for that, proper literature study of what is already known, what research has been already done is necessary. Background research will help to make out what has not been answered and to design an experiment accordingly.
