Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.283\% 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) CCOC(=O)C1CCN(C(=O)C(CCSC)NC(=O)COc2ccccc2)CC1
(b) O=C(Cn1cccc(C(F)(F)F)c1=O)c1ccc(Cl)cc1
Answer: b. O=C(Cn1cccc(C(F)(F)F)c1=O)c1ccc(Cl)cc1
