Task: Answer the multiple choice question.
Query: Which compound exhibits a -7.490\% 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: CCCCNC(=O)C1CC(=O)N(c2ccc(OC)cc2)C1c1ccc(OC)cc1
b: CC1(c2ccc(Cl)cc2Cl)OCC(Cn2cncn2)O1.O=[N+]([O-])O
c: COc1ccc([N+](=O)[O-])c2c(=O)ccoc12
Answer: c. COc1ccc([N+](=O)[O-])c2c(=O)ccoc12
