Task: Answer the multiple choice question.
Query: Which compound has a 1.660\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CN1C(C(=O)NCc2cccc(Br)c2)CC2Cn3c(nc4cc(Cl)c(Cl)cc43)C21
b: COc1ccc(NC(=O)CN(Cc2ccccc2)S(C)(=O)=O)c(OC)c1
Answer: b. COc1ccc(NC(=O)CN(Cc2ccccc2)S(C)(=O)=O)c(OC)c1
