Problem statement: Answer the multiple choice question.
Question: Which drug has a 20.367% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) O=C(OCCN1C(=O)c2ccccc2C1=O)c1ccco1
b.) CCOC(=O)N1CCC(Nc2c([N+](=O)[O-])cc(C(=O)O)cc2[N+](=O)[O-])CC1
Answer: b. CCOC(=O)N1CCC(Nc2c([N+](=O)[O-])cc(C(=O)O)cc2[N+](=O)[O-])CC1
