Task: Answer the multiple choice question.
Query: Which compound exhibits a -3.656% 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 CCNC(=S)N1CCC(c2nc3cc(C)c(C)cc3[nH]2)CC1.O=C(O)C(=O)O
b CCOC(=O)Cn1cc(/C=C/[N+](=O)[O-])c2ccccc21
Answer: b. CCOC(=O)Cn1cc(/C=C/[N+](=O)[O-])c2ccccc21
