Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.273\% 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(O)C(=O)O.OCCNCCCCOc1cccc(Br)c1
[b] Cc1ccc(C(=O)CCC(=O)Nc2ncccc2C)cc1
[c] Cn1c(=O)c2c(nc(NCc3ccco3)n2C)n(C)c1=O
Answer: a. O=C(O)C(=O)O.OCCNCCCCOc1cccc(Br)c1
