Task: Answer the multiple choice question.
Question: Which drug has a 17.299\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CS(=O)(=O)N1CCN(C(=O)CSc2ccccc2)CC1
b: COc1ccc(NS(=O)(=O)c2ccc(NC(C)=O)cc2)nn1
c: CC(C)(C)c1ccc(-c2nc(C=O)c3ccccn23)cc1
Answer: a. CS(=O)(=O)N1CCN(C(=O)CSc2ccccc2)CC1
