Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.829% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CC1(C)C2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])CN(CCO)C2
(b) COc1cc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2CCN2CCOCC2)cc(OC)c1OC
Answer: a. CC1(C)C2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])CN(CCO)C2
