A. The President-elect dies (or resigns) between the electoral college vote and inauguration
"If, at the time fixed for the beginning of the term of the President, the President elect shall have died, the Vice President elect shall become President." That's the twentieth amendment, section 3.

Unclear. As you pointed out, the 1872 election is our only guide. From that, we can surmise that the electors will be free to vote for anyone they want (but then, of course,
they're already free to vote for anyone they want).

Again, that's unclear. Different states have different laws.
This article answers -- or doesn't answer -- a lot of these questions.

A disaster of biblical proportions. Dogs and cats living together. Mass hysteria.

Yes, but no one noticed.
