Task: Answer the multiple choice question.
Query: Which compound exhibits a -69.114% 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 additional words.
Options:
a: O=C(OCc1ccc([N+](=O)[O-])cc1)C1CC(=O)N(c2ccccc2)C1
b: CCOc1c(Br)cc(C2CC(=O)Nc3cc(OC)c(OC)cc32)cc1OC
c: C=CCN(c1ccc(C(=O)NCCN2CCOCC2)cc1)S(C)(=O)=O
Answer: a. O=C(OCc1ccc([N+](=O)[O-])cc1)C1CC(=O)N(c2ccccc2)C1
