Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 9.275\% 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. CN(C)CCCN1C(=O)C(O)=C(C(=O)c2cccs2)C1c1cccc([N+](=O)[O-])c1
b. CC(=O)NCc1cc(-c2nn(C)c(=O)c3ccccc23)ccc1C
Answer: a. CN(C)CCCN1C(=O)C(O)=C(C(=O)c2cccs2)C1c1cccc([N+](=O)[O-])c1
