A) Completely fucked. Likely dead within days.

B) Less fucked than most I imagine. I do a lot of hiking (multiple times a week) and carry the 10 essentials in my bag, including a water filter. Food would be the biggest issue as I typically only have one meal and some snacks in my bag. I think it's doable though.

C) I think I'd be fine. I have enough food to last for months if I ration it and the knowledge, seeds and tools to grow a pretty robust heirloom garden. I also have water filtration and backups, as well as tents for shelter, solar rechargeable batteries for light at least until the panels and batteries degrade, and hand tools to build a more robust shelter. If the contents of my whole house came though the difficulty would be feeding my dog and cat, so we'd have to quickly start working on figuring out how to get meat regularly. I'd have about 2 months of food for them, but that would go quick. I am not readily equipped for hunting so I'd have to cobble together some snares. I have Wikipedia downloaded to an old Kindle and that would probably help in that department. I think in this scenario I'd be fine until disease got me. I have emergency antibiotics in my house though so I could at least survive a couple rounds of bacterial diseases.
