Task: Answer the multiple-choice question.
Query: Which drug has a 6.816\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1ccc(O)cc1C(=O)O
b) CCC(=O)N1CCc2cc(S(=O)(=O)NCCC(=O)Nc3ccccc3C)ccc21
Answer: a. O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1ccc(O)cc1C(=O)O
