Task: Answer the multiple choice question.
Question: Which compound has a 14.151\% 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([N+](=O)[O-])cc1NC(=O)COC(C)=O
(b) COc1ccc(-c2ncncc2-c2csc(C)n2)c(O)c1OC
(c) CC(Nc1nc2ccccc2n2cnnc12)c1ccccc1
Answer: a. COc1ccc([N+](=O)[O-])cc1NC(=O)COC(C)=O
