Task: Answer the multiple-choice question.
Query: Which drug has a -8.142\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCc1ccc(NC(=O)Cc2cn(C)c3ccccc23)cc1
[b] O=C(c1ccc(Cl)s1)N1CCN(c2nc3ccccc3s2)CC1
[c] O=C(OCc1ccc([N+](=O)[O-])cc1Cl)c1cnccn1
Answer: b. O=C(c1ccc(Cl)s1)N1CCN(c2nc3ccccc3s2)CC1
