Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.077\% human ether-à-go-go related gene (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: CCN(CC(=O)N1CCN(C)CC1)S(=O)(=O)c1ccc(Cl)cc1
b: CC(C)(C)C(=O)Nc1ccc(/C=C/C(=O)c2ccco2)cc1
Answer: a. CCN(CC(=O)N1CCN(C)CC1)S(=O)(=O)c1ccc(Cl)cc1
