Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.954\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CC(=O)c1c(C)nn(CC(O)Cn2c3c(c4cc(C)ccc42)CCCC3=O)c1C
(b) CCCCN(C)S(=O)(=O)c1cc(Br)cc2c1N(C(=O)C1CC1)CC2
Answer: a. CC(=O)c1c(C)nn(CC(O)Cn2c3c(c4cc(C)ccc42)CCCC3=O)c1C
