Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.609\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CN(Cc1ccccc1)C(=O)CCC(=O)N(C)Cc1ccccc1
b O=C1CS/C(=C\[N+](=O)[O-])N1c1ccc(OC(F)(F)F)cc1
Answer: b. O=C1CS/C(=C\[N+](=O)[O-])N1c1ccc(OC(F)(F)F)cc1
