I think D & E should be eliminated because: I know that if I had enough
technology to either leave the Universe or make my civilization so
advanced that it would seem to disappear, I would first before doing
that create and send out an armada of self replicating smart probes into
space to seek out and help all other life forms in the Universe. The
only way to keep D & E on your list is to posit that none of the aliens
out there do this for some unknown reason.

Also F should not be "low", but "zero". It only takes one.

I think A & B have been eliminated AFAIK by known physics and other science.

That leaves C or "we live in a simulation" or other unpleasantness I think.
