Step-by-step explanation:
The pre-writing activity demonstrated in the question appears to be outlining the main points of the essay.
This is evident from the instruction to start organizing the big ideas of the essay once some basic ideas have been noted down. Outlining is a crucial step in the writing process because it helps in structuring the essay logically and making it easier to introduce the writer's ideas coherently when the time comes to draft the actual essay.
The writing process generally includes several steps, which are often recursive and may involve brainstorming for initial ideas, creating an outline to organize those ideas, the actual drafting of the essay, and finally, revising and editing the content to polish and improve the write-up.
Each of these steps is important, and different writers may find different strategies that work best for them. However, outlining serves as a framework that guides the flow of the essay and is particularly useful in organizing thoughts before drafting.
It's also important to note that during brainstorming, a writer quickly jots down all possible ideas and then begins the process of organizing and narrowing down those ideas to form a more coherent essay topic.
So Option c.
