Task: Answer the multiple-choice question.
Query: Which compound exhibits a 15.844\% 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 N[C@@H](Cn1oc(=O)[nH]c1=O)C(=O)O
b O=[N+]([O-])c1ccc(Nc2ccc(Oc3ccc([N+](=O)[O-])cc3[N+](=O)[O-])cc2)c([N+](=O)[O-])c1
Answer: a. N[C@@H](Cn1oc(=O)[nH]c1=O)C(=O)O
