Task: Answer the multiple choice question.
Question: Which compound has a -2.485\% 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: Cc1cc(C(F)F)nn1CC(=O)Nc1cc([N+](=O)[O-])ccc1F
b: CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2cn(C(C)=O)c3ccccc23)[C@@H]1CCCO
Answer: a. Cc1cc(C(F)F)nn1CC(=O)Nc1cc([N+](=O)[O-])ccc1F
