Task: Answer the multiple choice question.
Query: Which compound has a 2.042\% 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] COc1cccc(C(=O)Nc2cccc(NC(C)=O)c2)c1
[b] COC(=O)c1c(-c2ccco2)csc1NC(=O)C1CC=CCC1C(=O)O
[c] CCCn1c(SCC(=O)NCCc2ccccc2)nnc1-c1cccnc1
Answer: b. COC(=O)c1c(-c2ccco2)csc1NC(=O)C1CC=CCC1C(=O)O
