A=1 and C=1 so, it's complement is going to be 0.
B and D is already zero. Therefore in sum all are zero produces the result zero.

A = 1 it will be negated to 0 C = 1 it will also be negated to 0 therefore the expression has OR operator:
A + B + C + D = 0 when,
A = 0 B = 0 C = 0 D = 0 because OR operator takes the favor of 1,
0 + 0 + 0 + 0 = 0.
A + B + C + D = 0 when,
A = 0 B = 0 C = 0 D = 0 because OR operator takes the favor of 1,
0 + 0 + 0 + 0 = 0.

Sop (sum of products)
Minterm A^=1.
A=O.
POS (product of sum)
Maxterm A^=0,
A=1.
Minterm A^=1.
A=O.
POS (product of sum)
Maxterm A^=0,
A=1.

Since we have to get the sum as 0 so we have to convert all the inputs into 0 so for A bar to be 0 we have to take A as 1 and for B there is no bar means inversion so we take it as 0 only do it in the same way for the other.

Anwser is B, It's Correct because for getting zero in exp of addition, all terms must be zero so A' C' must be 1 so their compliment is zero. And b and c and d are zero.

Answer is B, Because for getting sum zero A' and C' must be one, because it's compliment is zero and B, D is zero.
