Task: Answer the multiple choice question.
Query: Which compound has a -55.657% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CN(C)C(=O)Oc1cc(OC(=O)N(C)C)cc(C(O)CNC(C)(C)C)c1.Cl
b: O=C(NCCN1CCN(c2ccccc2)CC1)Nc1cccc(Cl)c1
c: Cc1sc2nc(SCc3nc4ccccc4[nH]3)n(Cc3ccco3)c(=O)c2c1C
d: COc1ccc(S(=O)(=O)N2CCC(C(=O)OCC(=O)c3ccccc3)CC2)cc1[N+](=O)[O-]
Answer: b. O=C(NCCN1CCN(c2ccccc2)CC1)Nc1cccc(Cl)c1
