Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 11.396\% 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] CC(=O)c1ccc(NC(=O)Nc2cccc(Cl)c2)cc1
[b] O=C(CNC(=O)c1cccc(F)c1)N/N=C/c1cccc([N+](=O)[O-])c1
Answer: a. CC(=O)c1ccc(NC(=O)Nc2cccc(Cl)c2)cc1
