Task: Answer the multiple-choice question.
Question: Which drug has a 17.531\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc2nc(COC(=O)c3cccc([N+](=O)[O-])c3)c(C(C)=O)[n+]([O-])c2c1
b: COc1ccc(C(=O)Nc2nc(-c3ccc([N+](=O)[O-])cc3)c(-c3ccc(OC)cc3)s2)cc1
Answer: a. COc1ccc2nc(COC(=O)c3cccc([N+](=O)[O-])c3)c(C(C)=O)[n+]([O-])c2c1
