What rule is this?

After watching the video explanation, I have a question in mind. Though I understand the logic behind the right answer, I need your help to understand what rule we used in finding the right answer. Let's use MCA=mail correctly addressed; M=mail; we have 1. MCA -most- in2day 2. M - most - out2day 3. M - some - MCA and we somehow concluded that Answer D is correct by saying: M - some - Not MCA. How did we get this? And please let me know if my diagram of answer D is correct. Thank you

I think it should be noted that in2day is the logical opposition of out2day. But I still don't get how we arrived at the correct of D though

@NativeJustice please refer to the previous discussion threads as well as the video explanation, which explains in detail how we arrived at the correct answer.

Hope this helps! Please let us know if you have any other questions.

@mehran
Thank you very much for your reply. I think I should clarify my confusion here. I do understand the process of how we arrived at the correct answer. And I think your explanation was very clear, which I really appreciate.

But I think this might be some kind of hidden rule that wasn't summarized. I thought the rules for making valid deductions with quantifiers in your video were able to comprehensively cover all scenarios, but here in this question, for the correct answer, we have to rely on extra logic and understanding rather than pure rules calculation.
It might also because the "nearly all" and "large proportion" phrase throw everyone off.
could you please explain. Thank you a ton.

I mean, could you please explain what rules were used for the correct answer, or this is one of the cases where we have to think outside the rules and logically try to make sense of it.
