Task: Answer the multiple-choice question.
Question: Which drug has a 11.846\% 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: CN(CC(=O)Nc1ccc(F)cc1)C(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1
b: O=C(NCCCl)C1Cc2c(ccc3ccccc23)O1
Answer: b. O=C(NCCCl)C1Cc2c(ccc3ccccc23)O1
