Task: Answer the multiple choice question.
Question: Which compound exhibits a -20.726% 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 CN(C)C(=O)Oc1cccc([N+](C)(C)C)c1.[Br-]
b CC1=C(C(=O)OCc2ccc3c(c2)OCO3)C(c2ccc(Cl)cc2)NC(=O)N1
c C[C@@H](C(=O)NC1CCCCC1)N1C(=O)N2CCc3c([nH]c4ccccc34)[C@@]2(C)C1=O
Answer: c. C[C@@H](C(=O)NC1CCCCC1)N1C(=O)N2CCc3c([nH]c4ccccc34)[C@@]2(C)C1=O
