Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.947\% hERG inhibition at 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)[nH]c(C(=O)COc2ccc(C#N)cc2)c1C
b) Cc1cc2cc(CNC(=O)Nc3ccccc3)ccc2[nH]1
Answer: a. CC(=O)c1c(C)[nH]c(C(=O)COc2ccc(C#N)cc2)c1C
