Task: Answer the multiple choice question.
Query: Which drug has a 6.248% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(COc1ccccc1)Nc1ccc(-c2nnc(-c3ccco3)o2)cc1
b. CCOc1ccc(Br)cc1S(=O)(=O)N1CC(C)OC(C)C1
Answer: a. O=C(COc1ccccc1)Nc1ccc(-c2nnc(-c3ccco3)o2)cc1
