Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.937\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC1Cn2c(nnc2C(=O)c2ccccc2)S1
[b] O=C1NC(=O)C(=Cc2ccc(OCCOc3ccc([N+](=O)[O-])cc3)cc2)C(=O)N1
[c] Cc1cc(C)nc(SCc2nnc(SCC#N)n2-c2cccc(Cl)c2)n1
Answer: b. O=C1NC(=O)C(=Cc2ccc(OCCOc3ccc([N+](=O)[O-])cc3)cc2)C(=O)N1
