Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.587\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCC(C)NS(=O)(=O)c1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)cc1
(b) Nc1c(Cl)cc(C2=NCCn3nc4cc([N+](=O)[O-])ccc4c32)cc1Cl
Answer: a. CCC(C)NS(=O)(=O)c1ccc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)cc1
