Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.125\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] Cc1cc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)no1
[b] O=C1NC(=O)C(=Cc2ccc3c(c2)OCO3)C(=O)N1
Answer: a. Cc1cc(NC(=O)c2ccc([N+](=O)[O-])cc2Cl)no1
