Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.430\% 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 other words.
Options:
[a] CCCC(=O)Nc1nc2c(ccc3onc(-c4ccccc4[N+](=O)[O-])c32)s1
[b] Cn1c(SCc2cccc([N+](=O)[O-])c2)nc2ccccc2c1=O
Answer: b. Cn1c(SCc2cccc([N+](=O)[O-])c2)nc2ccccc2c1=O
