Problem statement: Answer the multiple choice question.
Question: Which compound has a 13.543\% 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 other words.
Options:
a. CCOC(=O)COc1c(Br)cc(/C=C2\SC(=O)N(CC(=O)N3CCCC3)C2=O)cc1OC
b. CC(C)Cn1c([N+](=O)[O-])nc2c1c(=O)[nH]c(=O)n2C
c. O=C(CN1C(=O)/C(=C/c2ccco2)SC1=S)Nc1ccc(O)c(C(=O)O)c1
Answer: b. CC(C)Cn1c([N+](=O)[O-])nc2c1c(=O)[nH]c(=O)n2C
