Task: Answer the multiple-choice question.
Query: Which compound exhibits a 9.281\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) C=Cn1nc(C)c2ccccc2c1=O
(b) O=C(c1ccc(F)cc1)N1CCN(c2ccc([N+](=O)[O-])c(N3CCCCC3)c2)CC1
(c) C/C(CC(=O)Nc1cccc(Cl)c1Cl)=N\NC(=O)c1ccccc1C
Answer: b. O=C(c1ccc(F)cc1)N1CCN(c2ccc([N+](=O)[O-])c(N3CCCCC3)c2)CC1
