Problem statement: Answer the multiple-choice question.
Query: Which drug has a 15.837\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOCCn1c(CN2CCN(c3ccccc3)CC2)nc2c1c(=O)n(C)c(=O)n2C
b: CCOC(=O)c1ccc(S(=O)(=O)N2CCN(C(=O)/C=C/c3ccccc3OC)CC2)cc1
c: O=C(NCc1ccc(Cl)cc1)c1cc([N+](=O)[O-])ccc1Cl
d: O=C1NN(c2ccccc2)C(=O)C2C3C=CC(C4CC34)C12
Answer: c. O=C(NCc1ccc(Cl)cc1)c1cc([N+](=O)[O-])ccc1Cl
