Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.490\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCC1(c2ccccc2)NC(=O)N(CC(=O)c2ccc3c(c2)OCO3)C1=O
[b] CN(CC(=O)Nc1ccccc1[N+](=O)[O-])Cc1ccc(Br)cc1
Answer: b. CN(CC(=O)Nc1ccccc1[N+](=O)[O-])Cc1ccc(Br)cc1
