Boolean Algebra and Logic Simplification

Q1:

Determine the binary values of the variables for which the following standard POS expression is equal to 0. 

A (0 + 1 + 0)(1 + 0 + 1)

B (1 + 1 + 1)(0 + 0 + 0)

C (0 + 0 + 0)(1 + 0 + 1)

D (1 + 1 + 0)(1 + 0 + 0)

ANS:A - (0 + 1 + 0)(1 + 0 + 1)

I think A is Correct bcoz the given binary values represent the values for the inputs (A,B,C), then
(0+1+0)=> for (A+B'+C)=(0+0+0)=0&
(1+0+1)=>for (A'+B+C')=(0+0+0)=0 so;
(A+B'+C).(A'+B+C')= 0.0 = 0.
