Task: Answer the multiple choice question.
Question: Which compound has a 4.626\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) NC(=O)COC(=O)c1cccc(S(=O)(=O)N2CCCc3ccccc32)c1
(b) O=C(Oc1ccc2c(c1)OCO2)c1ccc(F)cc1Cl
(c) C=CCN(CC=C)C(=O)Nc1cc(Cl)ccc1OC
Answer: c. C=CCN(CC=C)C(=O)Nc1cc(Cl)ccc1OC
