Task: Answer the multiple choice question.
Query: Which compound exhibits a -3.234\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] COc1cccc(N(CC(=O)Nc2ccccc2C(=O)N2CCCC2)S(C)(=O)=O)c1
[b] O=C(NC1CCCC1)c1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1
Answer: b. O=C(NC1CCCC1)c1ccc2nc(-c3ccco3)c(-c3ccco3)nc2c1
