Task: Answer the multiple choice question.
Question: Which drug has a 13.227\% 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 or b without using any additional words.
Options:
[a] COc1ccc(CNC/C=C/c2ccccc2)cc1.Cl
[b] CCCOC(=O)c1c(NC(=O)CCCn2nc([N+](=O)[O-])cc2C)sc(C(=O)OC)c1C
Answer: b. CCCOC(=O)c1c(NC(=O)CCCn2nc([N+](=O)[O-])cc2C)sc(C(=O)OC)c1C
