The recent U.S. Supreme Court ruling that addressed Section 3 of the 14th Amendment and declared that they're only enforceable by Congress really opens a can of worms.

It sounds to me like the 22nd Amendment and the Article II natural-born citizenship requirement are also only enforceable by Congress. If you're making your plans based on a theory that Congress is able to do the right thing, or that the Supreme Court is not a hyper-partisan institution, I would have a strong C because plans A and B are pretty questionable.
