So, please correct me if I am wrong
from 3 (-1)^0 is -1; well it should be 1.
from 1, (-1)^(-1) should be -1
as (-1)^(-1)=1/(-1), so -1
Well the OA is not E but B? That's what I want to sort out.

OA is wrong. E must be it
III must also be true
Anything to the power 0 will be equal to 1
so (-1)^0 = 1
and 1 = -k = -(-1) = 1
