Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.150\% 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 CC(C)C(=O)N1CCN(c2ccc(NC(=O)c3ccc([N+](=O)[O-])o3)cc2)CC1
b CCCCc1ccc(S(=O)(=O)Nc2nnc(C)s2)cc1
Answer: a. CC(C)C(=O)N1CCN(c2ccc(NC(=O)c3ccc([N+](=O)[O-])o3)cc2)CC1
