Task: Answer the multiple choice question.
Query: Which drug has a 12.870% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(O)Cc1ccc(NC(=S)NCc2ccco2)cc1
(b) COc1cccc(Nc2nnc(SCc3cc([N+](=O)[O-])cc4c3OCOC4)s2)c1
Answer: a. O=C(O)Cc1ccc(NC(=S)NCc2ccco2)cc1
