Answer:
Generate a research question about your topic.
Explanation:
It is not "narrow down your research topic" because you have already created a research plan which means that you already know what your research topic is.
It is not "choose a topic that you find interesting" because you already have found a topic that is interesting since you already created a research plan on that topic.
It is not "synthesize facts from multiple sources" because you need to "generate a research question about your topic" in order to search up the facts from that question to answer the question.
