Task: Answer the multiple-choice question.
Question: Which compound exhibits a 9.729\% 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 CC(=O)Nc1ccc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NCc2ccco2)c2ccccc2)cc1
b O=C(Nc1ccc(-c2nnc(-c3ccccc3)o2)cc1)C(F)(F)F
Answer: b. O=C(Nc1ccc(-c2nnc(-c3ccccc3)o2)cc1)C(F)(F)F
