Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 13.721% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(COc1ccc(/C=N/NC(=O)c2ccccc2O)cc1)Nc1ccc([N+](=O)[O-])cc1
(b) O=[N+]([O-])c1cccc(C=Nc2cc3c(cc2Br)OCCO3)c1
Answer: a. O=C(COc1ccc(/C=N/NC(=O)c2ccccc2O)cc1)Nc1ccc([N+](=O)[O-])cc1
