Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 16.250\% 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 additional words.
Options:
a. COc1ccccc1C(=O)NC(=O)COC(=O)CNC(=O)c1ccc(Cl)c([N+](=O)[O-])c1
b. CC(=O)NNc1cccc(Cl)n1
c. O=C1CN(c2ccccc2)C(=O)N1
Answer: c. O=C1CN(c2ccccc2)C(=O)N1
