Option 2, with the two extra votes assigned to whichever candidate wins the statewide vote, like Maine and Nebraska do. BTW, in 2012, if all states had used Option 2, Mitt Romney would have won the electoral college, 274 to 264. Romney won several more congressional districts than Obama.
An election in which Obama won the popular vote by 5,000,000, which makes this an example of why such a change would be unhelpful. Not only does it perpetuate the problem that comes with basing election results off of geography but it also makes presidential elections susceptible to gerrymandering. And option 1 sounds like an obvious recipe for corruption.
So, option 3 is of course the best, and the closest we could get to "fair" under the EC. Of course, doing this renders the college pointless (not necessarily a bad thing).
