Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a -13.507\% 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] C/C(=N/NS(=O)(=O)c1cccc([N+](=O)[O-])c1)c1ccc2c(c1)OCO2
[b] CC(=O)c1cc(C#N)c(SCC(=O)C(C)(C)C)nc1C
[c] O=C(O)C(=O)O.O=C(c1cccs1)N1CCN(Cc2cccc([N+](=O)[O-])c2)CC1
Answer: b. CC(=O)c1cc(C#N)c(SCC(=O)C(C)(C)C)nc1C
