The best analogy comparing an outline to a research paper is letter B: An outline is the skeleton and the research paper is the body. This is because skeleton is like a framework, the foundation of something, the fundamentality of creation. It is like the fundamental source of everything beautiful that is yet to grow. A default of a thing coming for beauty. It is something that came from something that we do not know yet if it is beautiful or not when it grows. But in the right time, everything about it will unravel, slowly but surely, like a flower, from being just a bud (skeleton) to becoming a flower with healthy petals (research paper).
