Even Russia and North Korea have not completely abolished “elections,” they maintain a laughable facade of “democracy.” 0% chance of option 3. Option 2 is a given however. Hopefully it will “just” be Trump doing everything he can to put his thumb on the scale but not to an insurmountable degree, and not outright rigging to ensure his preferred candidate wins no matter what. But unfortunately the latter cannot be ruled out given who we're talking about here.
I think the latter can be ruled out since Trump and the GOP don't have full control over elections in any swing state.
What are the odds of option 1?
