Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.414\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(NCC1COc2ccccc2O1)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
(b) Cc1ccc(S(=O)(=O)N=S(CC2CC2(Cl)Cl)CC2CC2(Cl)Cl)cc1
(c) O=C(NNS(=O)(=O)c1ccc(F)cc1)c1ccc2c(c1)OCO2
(d) Brc1ccc(-c2n(-c3ccccn3)c3ccccc3[n+]2-c2ccccn2)cc1.[I-]
(e) CCOC(=O)/C(C#N)=C/c1ccc(OC(=O)c2ccccn2)cc1
Answer: a. O=C(NCC1COc2ccccc2O1)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
