Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.503\% 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(NC(=O)C(C)OC(=O)c2ccc(C)s2)cc1
b O=C(CCS(=O)(=O)c1ccc(Br)s1)NC1CCCC1
Answer: b. O=C(CCS(=O)(=O)c1ccc(Br)s1)NC1CCCC1
