Determining the "most restrictive" answer choices?

@Mehran or anyone Can we please get an answer to this? I'm wondering the same too because I do agree that knowing the most restrictive answer choice will save a lot of time, but I was looking at option A, for example, because it involved G, which is a mini block that is normally restrictive, but as pointed out within the video, G isn't the most restrive answer choice, it was L. So what is a tip for me to know what answer choice is the most restrictive? Main question: Does the location within the sequence the ultimate factor on what makes a letter/rule super restricted or not? As in, should I be looking for answer choices that restrict the beginning or end section of a sequence if I am unsure which is the most restrictive answer choice?

You're not looking for restrictive answer choices, but knowing which rules are most restrictive helps us to prioritize answer choices to test our first. While g is more restrictive as a rule than the IL block, that doesn't guarentee a js the right answer. However I would still have tested out A first, and then tested out the IL answer choice. And yes, restrictive rules are ones that force the most other things to happen.
