Task: Answer the multiple choice question.
Question: Which compound exhibits a -66.538% 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] COc1ccc(CNS(=O)(=O)c2c(C(=O)N3CCCCC3)c(C)n(C)c2C)cc1
[b] CCN1CCCC1CNC(=O)c1ccc(Sc2ccc(F)cc2)c([N+](=O)[O-])c1
Answer: b. CCN1CCCC1CNC(=O)c1ccc(Sc2ccc(F)cc2)c([N+](=O)[O-])c1
