Task: Answer the multiple choice question.
Question: Which drug has a 13.571\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)c1ccc([N+](=O)[O-])cc1Cl
(b) O=C(Nc1ccc(Cl)cc1)N1CCCC(Cn2cccc2)C1
(c) COCCNC(=O)C(OC(=O)c1ccco1)c1ccccc1F
Answer: b. O=C(Nc1ccc(Cl)cc1)N1CCCC(Cn2cccc2)C1
