Step-by-step explanation:
The correct answer reflecting all of Professor Marcos Ojeda's guidelines for composing on the computer is Option B: Name and number each draft, print your work often, save your work often, and save your work in two places. These guidelines align with effective writing strategies such as creating paragraph outlines to map out a paper's structure, testing the evidence to ensure each piece is factual and supports the main idea, and remaining open to change by starting over if necessary. Additionally, securing your drafts by naming, numbering, and saving them in multiple locations is critical to prevent loss of work and facilitate the revision process.
