Problem statement: Answer the multiple choice question.
Question: Which drug has a -0.220\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] COc1ccc(N2CCN(C(=O)Cc3ccc(Cl)cc3)CC2)cc1
[b] O=C(NCc1cccs1)c1ccc([N+](=O)[O-])cc1
[c] O=C(Cc1n[nH]c(=O)c2ccccc12)Nc1cc(Cl)ccc1-n1cncn1
[d] CCOc1ccc(C(=O)/C=C/Nc2ccc(S(=O)(=O)N=C(N)N)cc2)cc1
[e] CCOC(=O)c1cnc(-n2nc(C)cc2C)[nH]c1=O
Answer: b. O=C(NCc1cccs1)c1ccc([N+](=O)[O-])cc1
