Task: Answer the multiple-choice question.
Question: Which compound exhibits a -11.639% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CC(C(O)c1cc(=O)c(OCc2ccccc2)co1)[N+](=O)[O-]
b) O=C(Nc1cccc([N+](=O)[O-])c1)NC1CCS(=O)(=O)C1
c) Cc1ccc(C(=O)Nc2nc(C)c(C)s2)o1
Answer: b. O=C(Nc1cccc([N+](=O)[O-])c1)NC1CCS(=O)(=O)C1
