Problem statement: Answer the multiple choice question.
Query: Which drug has a -28.458\% 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] O=C(NNC(=O)c1ccc2c(c1)OCO2)NC12CC3CC(CC(C3)C1)C2
[b] Cn1cnc([N+](=O)[O-])c1Sc1ccc([N+](=O)[O-])cc1
Answer: b. Cn1cnc([N+](=O)[O-])c1Sc1ccc([N+](=O)[O-])cc1
