Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.327% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CC1SC2=NCCN2C1=O)Nc1ccc(Br)cc1
[b] COc1ccc(-n2nc3c(c2NC(=O)c2ccc(Br)o2)CS(=O)(=O)C3)cc1
Answer: a. O=C(CC1SC2=NCCN2C1=O)Nc1ccc(Br)cc1
