Nice problem :3
I will be the first one solve it :v
using (1):
we have B is not an odd integer => B is an even integer => not sufficient
using (2):
we have A+B is an odd integer => not sufficient
combine (1) and (2):
A + B = odd integer
=> A + even integer = odd integer
by using this formula : odd + even = odd (example: 5 + 2 =7)
=> A is an odd integer (you will be even next time A
) => sufficient
=> answer is C

I would also vote for C
Since B is not an odd integer then it definitely an even ( 0 zero also an even) , so from A & B A can be found weather it's even or odd
