Task: Answer the multiple-choice question.
Question: Which drug exhibits a 9.392\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C1CSC(=Nc2ccccc2[N+](=O)[O-])N1
b) COc1ccc(NC(=O)COC(=O)CNS(=O)(=O)c2ccccc2)cc1OC
c) Cc1ccccc1NC(=O)C1CCN(C(=O)NC2CCCCC2)CC1
Answer: a. O=C1CSC(=Nc2ccccc2[N+](=O)[O-])N1
