Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.053\% 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 N#CC1=C(N)N(c2ccc(F)cc2)C(=O)C1
b O=C(Cn1cnc2cc([N+](=O)[O-])ccc2c1=O)Nc1ccc(N2CCOCC2)cc1
Answer: b. O=C(Cn1cnc2cc([N+](=O)[O-])ccc2c1=O)Nc1ccc(N2CCOCC2)cc1
