Task: Answer the multiple-choice question.
Query: Which compound exhibits a 0.326\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(O)C(=O)/C(=C\c1ccccc1)c1ccc2ccccc2n1
(b) CC1CCN(c2ccc(C(=O)NCc3ccco3)cc2[N+](=O)[O-])CC1
(c) CCC(COC)Oc1cc(NCc2ccccc2)c2ncn(C(C)C)c2c1
(d) CCOC(=O)C1=C(CSc2nc(-c3ccncc3)ccc2C#N)OC(N)=C(C#N)C1c1ccc(OC)cc1
Answer: b. CC1CCN(c2ccc(C(=O)NCc3ccco3)cc2[N+](=O)[O-])CC1
