Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.276\% 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) COc1cccc(Cn2c(NCc3ccco3)nc3c2c(=O)n(C)c(=O)n3C)c1
b) O=C(N/N=C/c1ccc[nH]1)c1ccc([N+](=O)[O-])cc1
c) CCOc1ccc(NC(N)=O)cc1OCC
Answer: a. COc1cccc(Cn2c(NCc3ccco3)nc3c2c(=O)n(C)c(=O)n3C)c1
