Okay, I’m going to help you a little here. The answer is D. “Proportions don’t matter when it comes to the first design of a sketch.” If you think about it, it won’t ever be proportional. Just like a first draft of a paper, it will never be perfect for the first try. When sketching, proportions are for the later steps, and not to focus on when your sketching out your first image.
For your bonus question, “Sketches differ with different clothing and designers.” Is definitely true. The sketches and designs will differ for each person, and will never be an exact replica.
