Task: Answer the multiple choice question.
Question: Which compound exhibits a 7.058% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CC(NC(=O)c1ccco1)C(=O)OC(C)C(=O)NCc1ccccc1
[b] O=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1
Answer: b. O=c1[nH]c(/C=C/c2ccccc2Cl)c([N+](=O)[O-])c(=O)[nH]1
