Task: Answer the multiple choice question.
Query: Which drug has a 13.423\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cc1nc2ccccc2c(=O)n1/N=C/c1ccccc1O
b: CCC(COC(=O)Nc1ccc(Cl)cc1)N1C(=O)CSC1c1ccc(C)cc1
c: O=C(COC(=O)c1cccc([N+](=O)[O-])c1)c1ccc(OCc2ccccc2)cc1
d: COc1ccccc1NC(=O)CSc1nc(O)cc(=O)n1-c1ccccc1OC
Answer: c. O=C(COC(=O)c1cccc([N+](=O)[O-])c1)c1ccc(OCc2ccccc2)cc1
