Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 16.896\% 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) CN1CC2(C)CN(C(c3ccccc3)c3ccccc3)CC(C)(C1)C2O
b) COC(=O)C1=CN(c2ccc(OC)cc2)C=C(C(=O)OC)C1c1ccc([N+](=O)[O-])cc1
Answer: b. COC(=O)C1=CN(c2ccc(OC)cc2)C=C(C(=O)OC)C1c1ccc([N+](=O)[O-])cc1
