Task: Answer the multiple choice question.
Query: Which drug exhibits a -66.630% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCN1CC(c2nc3ccccc3n2CCOc2ccccc2)CC1=O
b: CCc1nnc(NC(=O)CSc2nnc3ncccn23)s1
c: Cl.O=C(NN1CCN(Cc2ccccc2)CC1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
d: C=CCN1C(=O)C(CC(=O)Nc2ccc(OCC)cc2)N(Cc2ccccn2)C1=S
Answer: c. Cl.O=C(NN1CCN(Cc2ccccc2)CC1)c1ccc(N2CCOCC2)c([N+](=O)[O-])c1
