Answer:
(A) Even
Step-by-step explanation:
We can try out 3 cases here:
1. M and N are even
2. M and N are odd
3. M is even and N is odd
For case 1, we can try 2 and 4 - 6*8=48
For case 2, we can try 1 and 3 - 3*4=12
For case 3, we can try 1 and 4 - 5*4=20
All of our answers are even, and if you keep the parity the same, but input different values for M and N for all cases, we are just adding 2, and thus, keeping the equation the same. Thus, our answer is A.
