Task: Answer the multiple choice question.
Question: Which compound has a -0.089\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCN(CC(=O)NCc1cccs1)C(=O)c1ccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)cc1
b. CC(/C=C/c1ccco1)=N\NC(=O)COc1ccc(C)c(C)c1
c. O=C1CCC(C(=O)N2CCc3ccccc3C2)CN1CCCN1CCOCC1
Answer: a. CCN(CC(=O)NCc1cccs1)C(=O)c1ccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)cc1
