orgo (fischer) question

Just checking if anyone has an efficient way to orient bond/line to fischer projections? I imagined the tetrahedral bond orientation at the chiral carbon and kind of turned my head to the right. I admit I was handicapped in undergrad and got to use a molecule set on tests 🙂

I think the easiest way is to not use a Fischer projection at all. I don't think it's necessary to do that to answer this question. I think you can answer simply using the process of elimination. I never learned Fischer and didn't have to use it at all.
