Problem statement: Answer the multiple choice question.
Query: Which drug has a 13.139\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC1=C(C)C(C)=C(C#N)C(=C(C#N)C#N)N1
[b] CC(Oc1ccccc1)C(=O)Nc1cccc([N+](=O)[O-])c1
Answer: a. CC1=C(C)C(C)=C(C#N)C(=C(C#N)C#N)N1
