Task: Answer the multiple-choice question.
Question: Which compound has a 2.131\% 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] O=C(Nc1ccc(OC(F)(F)F)cc1)c1cnc2n(c1=O)CCS2
[b] CSc1ccc(-c2nc3cnccn3c2Nc2ccc3c(c2)OCO3)cc1
[c] CCOCCCNCc1ccc(OCCC(C)C)c(OC)c1.O=C(O)C(=O)O
Answer: c. CCOCCCNCc1ccc(OCCC(C)C)c(OC)c1.O=C(O)C(=O)O
