Task: Answer the multiple-choice question.
Query: Which compound exhibits a 14.520\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cc1ccc2c(c1)CC1(CN2C)C(=O)NC(=O)N(c2cc(C)ccc2C)C1=O
[b] O=C(Oc1ccc([N+](=O)[O-])cc1)c1ccc(Cl)c(S(=O)(=O)N2CCCCC2)c1
[c] CCN(CC)CCCN=C1N[C@@H](c2ccccc2)C(C(=O)OC)=C(C)N1CC
[d] COC(=O)CC(c1ccc(OC)c(OC)c1)c1ccc(OC)c(OC)c1
Answer: b. O=C(Oc1ccc([N+](=O)[O-])cc1)c1ccc(Cl)c(S(=O)(=O)N2CCCCC2)c1
