what a weird problem.

i guess (a) would be more accurate if it said "is buried", because he's still buried there -- i.e., no one has exhumed his body from the ground.
but the problem is still problematic, because "was buried" can also refer to the physical act of burying the poet, in which case (a) makes perfect sense.

so, i would say:
* disregard this problem
* be suspicious of this source from now on.
