Problem statement: Answer the multiple choice question.
Query: Which compound has a 19.998% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CCn1c(=NC(=O)CCS(=O)(=O)c2ccccc2)sc2cccc(OC)c21
b. Cc1ccc(CNC(=O)Cc2noc3ccccc23)cc1
c. O=C(Cc1ccc([N+](=O)[O-])cc1)NCc1ccccc1Cl
d. CCO[C@@H]1OC(C(N)=O)=C[C@H](c2ccccc2)[C@H]1CCCO
e. O=C(/C=C\Nc1ccccc1Br)c1ccc2c(c1)OCO2
Answer: c. O=C(Cc1ccc([N+](=O)[O-])cc1)NCc1ccccc1Cl
