Task: Answer the multiple choice question.
Question: Which drug has a 12.356\% 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: O=C(CNC(=O)N1CC(=O)Nc2ccccc21)Nc1ccccc1F
b: O=C(C1CCC1)N1CCCc2cc(S(=O)(=O)N3CCN(c4ccccc4)CC3)ccc21
Answer: a. O=C(CNC(=O)N1CC(=O)Nc2ccccc21)Nc1ccccc1F
