Task: Answer the multiple choice question.
Question: Which drug has a 9.685\% 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) Cc1ccsc1/C=C1\SC(=S)N(CC2CCCO2)C1=O
(b) CN(CC(=O)Nc1ccc([N+](=O)[O-])cc1Br)Cc1c(F)cccc1Cl
Answer: b. CN(CC(=O)Nc1ccc([N+](=O)[O-])cc1Br)Cc1c(F)cccc1Cl
