Task: Answer the multiple choice question.
Question: Which compound exhibits a 6.595\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCC1=Nc2cc(C(=O)NCc3ccco3)ccc2Sc2ccccc21
[b] O=C(O)c1cc(/C=C/C(=O)c2cc(F)ccc2O)c2c(c1)COCO2
Answer: a. CCC1=Nc2cc(C(=O)NCc3ccco3)ccc2Sc2ccccc21
