Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.439\% 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: COc1ccc(Nc2sc(C(=O)c3ccc(Cl)cc3)c(N)c2C(=O)Nc2ccccc2OC)cc1
b: COc1ccccc1N(CC(=O)N1CCCCCC1)S(C)(=O)=O
c: O=C(c1ccc(S(=O)(=O)c2cccc(Cl)c2)c([N+](=O)[O-])c1)N1CCN(c2ccccn2)CC1
Answer: c. O=C(c1ccc(S(=O)(=O)c2cccc(Cl)c2)c([N+](=O)[O-])c1)N1CCN(c2ccccn2)CC1
