Task: Answer the multiple choice question.
Question: Which drug exhibits a 17.057\% 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=Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ncccn12
(b) COc1ccc(/C=C2/N=C3CCCCCN3C2=O)cc1OC
Answer: a. O=Nc1c(-c2cccc([N+](=O)[O-])c2)nc2ncccn12
