how to compare 3 list value with If condition

Here are my lists

    A = [32,33,34,35,36,37,38,39,40,41,42]
    B = [0, 0, 1, 0, 0, 0, 0, 0, 1, 0, 0]
    C = [0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0]
    D = [1, 1, 1, 2, 2, 1, 1, 1, 1, 1, 1]

Here, in list B value should be 0,in list C value should be 0 and in list D value should be 1 if this so then it is passed else failed. As you can see in list B index 2 value is 1 so it is failed like this in list C index 1 value is 1 instead of 0 and in list D index 3,4 value is 2 instead of 1. I've written the code for this but it is printing multiple time

my code-:

comment = "Wrong Signal in "
for first1 in A:
idx_val = A.index(first1)

    if (B[idx_val] != 0):
        comment = comment + 'B' 

    if C[idx_val] != 0:
        comment = comment + 'C' 

    if D[idx_val] != 1:
        comment = comment + 'D' 
print comment

Output-'Wrong Signal in B,C,D,D,B

But i'm expecting the output like this

Output- 'Wrong Signal in B,C,D

and another example if B list's all value are zeros and C,D has wrong value in any index then it should print

output -'Wrong Signal in C,D

Thank You In Advance
