Task: Answer the MCQ question.
Question: Which compound exhibits a -28.180\% 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 CCc1nc(SCC(=O)Nc2ccccc2Cl)n[nH]1
b COc1ccc(OC)c(-c2csc(N(C)C(=O)c3ccco3)n2)c1
c Cn1c(-c2cccc([N+](=O)[O-])c2)cnc1NCc1cccc([N+](=O)[O-])c1.O=C(O)C(=O)O
Answer: c. Cn1c(-c2cccc([N+](=O)[O-])c2)cnc1NCc1cccc([N+](=O)[O-])c1.O=C(O)C(=O)O
