Task: Answer the multiple choice question.
Query: Which compound has a 8.466\% 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: COc1cc(OC)cc(C(=O)NNC(=O)CNC(=O)c2cccs2)c1
b: COc1ccccc1-c1nc(SCC(=O)NCC2CCCO2)c2c(=O)n(C)c(=O)n(C)c2n1
c: O=C(CSc1nnc(-c2cccs2)n1-c1ccccc1)NCc1ccc2c(c1)OCO2
Answer: b. COc1ccccc1-c1nc(SCC(=O)NCC2CCCO2)c2c(=O)n(C)c(=O)n(C)c2n1
