Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.293\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C1C2C(C(=O)N1CCN1CCN(Cc3ccc([N+](=O)[O-])cc3)CC1)[C@H]1C=C[C@@H]2C1
b CC(C)(C)NC(=O)C1CCN(S(=O)(=O)c2cccc3nsnc23)CC1
c O=C(O)c1nc(-c2ccccc2)n(-c2ccc(Cl)cc2)n1
d O=[N+]([O-])c1ccc(S(=O)(=O)Nc2nc3ccccc3nc2Nc2ccccc2)cc1
Answer: d. O=[N+]([O-])c1ccc(S(=O)(=O)Nc2nc3ccccc3nc2Nc2ccccc2)cc1
