Task: Answer the multiple choice question.
Query: Which drug has a 13.066\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(N/N=C/c1ccc([N+](=O)[O-])cc1)c1cnccn1
b CC(C)CNC(=O)C1CCN(c2ccc(S(=O)(=O)N3CCOCC3)cc2Cl)CC1
Answer: a. O=C(N/N=C/c1ccc([N+](=O)[O-])cc1)c1cnccn1
