Problem statement: Answer the multiple choice question.
Question: Which drug has a 16.650\% 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] CC1(C)CC(NC(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)CC(C)(C)N1
[b] O=C(CN(Cc1ccco1)C(=O)c1ccc(F)cc1F)Nc1ccccc1C(F)(F)F
Answer: a. CC1(C)CC(NC(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2)CC(C)(C)N1
