The correct answer is 3. This makes sense since the two other positions mentioned increase the intradiscal pressure not only in L3 but also in all other L-spine disks. I am unable to scientifically prove my point neither since neither of the references mentioned in the answer are in the library nor could I not find anything about this topic in Miller of Spine OKU.
