Task: Answer the multiple choice question.
Query: Which drug has a 9.837\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(CN2C(=O)C3C4C=CC(C4)C3C2=O)cc1
b: O=C(NCCCc1ccccc1)C1CC(=O)N(c2ccc3c(c2)OCCO3)C1
c: CCOC(=O)C(CCCCCOc1ccccc1[N+](=O)[O-])C(=O)OCC
d: COc1ccc(-n2c(Cc3cccn3C)nnc2SCC(=O)NCc2ccccc2Cl)cc1
e: CCN(CC)C(=O)c1ccc(NC(=O)Nc2ccccc2F)cc1
Answer: c. CCOC(=O)C(CCCCCOc1ccccc1[N+](=O)[O-])C(=O)OCC
