I think it should be C

1) a can be 7 or a 156 or any number. If b or c =7, then the equation is
satisfied... SO INSUFF

2) INSUFF ..

Combined.. we know that b or c is not equal to 7 so we can now find a

from one

either bracket is = to zero

thus a could be 7 , b or c.insuff

bc = 18 = (9,2) or(18,1) 0r (6,3) .

insuff

both

b,c cant be 7 thus a is seven
my answer is C

C is my answer.
1 - says that atleast one out of a,b or c has to be 0.But cannot find value of a.
2 - says bc=18.But nothing about a.
Taking both together implies that none of b and c are 0. Hence a is 0.
