Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.009\% 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 COc1ccc(OC)c(NC(=O)c2cccc(C)c2[N+](=O)[O-])c1
b COc1ccc(NC2CCCN(C(=O)c3ccc(C(C)=O)cc3)C2)cc1
Answer: a. COc1ccc(OC)c(NC(=O)c2cccc(C)c2[N+](=O)[O-])c1
