Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.394\% 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) CC1CN(C(=O)COC(=O)c2cc([N+](=O)[O-])ccc2Cl)CC(C)O1
b) COc1ccccc1/C=C1\SC(=S)N(CCC(=O)NNC(=O)c2ccccc2O)C1=O
Answer: a. CC1CN(C(=O)COC(=O)c2cc([N+](=O)[O-])ccc2Cl)CC(C)O1
