Task: Answer the multiple choice question.
Query: Which drug has a 0.168% 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 COc1cccc(NC(=O)c2nn(C34CC5CC(CC(C5)C3)C4)cc2[N+](=O)[O-])c1
b O=C(c1ccccc1)c1ccc2nc[nH]c2c1
Answer: b. O=C(c1ccccc1)c1ccc2nc[nH]c2c1
