Task: Answer the multiple choice question.
Question: Which drug exhibits a -23.457\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) c1ccc(Cc2noc(CN3CCCCC3CCc3ccccn3)n2)cc1
b) CN(CC(=O)Nc1cccc(F)c1)C(=O)c1ccc(NC2CC2)c([N+](=O)[O-])c1
c) Cc1nc(Cl)c2c(n1)NC(=O)CO2
Answer: b. CN(CC(=O)Nc1cccc(F)c1)C(=O)c1ccc(NC2CC2)c([N+](=O)[O-])c1
