Task: Answer the multiple choice question.
Query: Which drug has a -18.672% 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(/C=C/c1ccc([N+](=O)[O-])cc1)N1CCN(S(=O)(=O)c2cccs2)CC1
b CCOC(=O)N1CCN(CC(=O)Nc2nc3ccccc3s2)CC1
Answer: a. O=C(/C=C/c1ccc([N+](=O)[O-])cc1)N1CCN(S(=O)(=O)c2cccs2)CC1
