I think there are a few moving parts that make it complicated.. Is this manager someone you want writing a LOR? if so, asking for the LOR seems like a good time to share your plan. If not, you probably would want to wait until you've been admitted AND secured your seat before quitting. Once you're committed to start at a school, 3 months feels more than adequate to me (personally, I even think 1 month would be appropriate). Unless you're in some sort of high leadership position that would take up to 6 months to recruit and hire someone, I don't see any reason why you'd be expected to give that much notice.

I feel better knowing that 59% of people also picked D <3

Spelling error in the last paragraph of the analysis of Answer D.... says "How that you see", but it should be "NOW that you see"
