Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.644\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(COc1cccc(Br)c1)NN=C1c2ccccc2-c2ccccc21
b: O=C(OCC(=O)N1CCN(C(=O)c2ccco2)CC1)c1ccccc1NCCO
c: COc1cc(N(C)C)c([N+](=O)[O-])cc1C(=O)N1CCOCC1
d: CC(=O)Nc1ccc(C(=O)OCc2ccc(Br)cc2)cc1
Answer: c. COc1cc(N(C)C)c([N+](=O)[O-])cc1C(=O)N1CCOCC1
