I think this is a trick question. None of the states have a contingent border. All the states borders have been established. Maybe the author of the question meant contiguous borders.

well
since borders are inherently contiguous
to describe them as contiguous would be meaningless
or redundant at best
&
in point of fact
a few state borders or segments of state borders are indeed indefinite or disputed etc
& therefore uncertain or conditional etc
so
contingent isn't necessarily meaningless in this connection
but the question is still tricky
for it certainly does not ask what state borders the most other states
as the above answer assumes
however
an exacting response is still possible
&
the correct answer very much appears to be Arkansas
which has no fewer than 3 contingent borders
namely
indefinite ones with Tennessee & Mississippi
according to usgs topos
probably because the center of the main channel of the Mississippi river has been so elusive
&
ever since the Oklahoma Texas state line was modified in 2000
a defective southernmost segment or tiny gap in the Arkansas border with Oklahoma as well
