Task: Answer the multiple-choice question.
Question: Which drug has a 9.930\% 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.) Cn1nnc(NC(=O)c2cccc([N+](=O)[O-])c2)n1
b.) COc1cccc(C(=O)N2CCN(Cc3ccc(OC)cc3OC)CC2)c1.O=C(O)C(=O)O
Answer: a. Cn1nnc(NC(=O)c2cccc([N+](=O)[O-])c2)n1
