Task: Answer the multiple-choice question.
Query: Which compound exhibits a 7.476\% 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 additional words.
Options:
a: CC(=NCCc1c(C)[nH]c2ccc(OCc3ccccc3)cc12)C1=C(O)CC(c2ccccc2)CC1=O
b: O=[N+]([O-])c1cccc(/C=N/Nc2nc(C(Cl)(Cl)Cl)nc3ccccc23)c1
c: CN(C)S(=O)(=O)c1ccc(C(=O)NCC2(N3CCCCC3)CCCCC2)cc1
Answer: b. O=[N+]([O-])c1cccc(/C=N/Nc2nc(C(Cl)(Cl)Cl)nc3ccccc23)c1
