Task: Answer the multiple-choice question.
Question: Which drug has a 7.072\% 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(OCc1ccc([N+](=O)[O-])cc1)c1cc2ccccc2oc1=O
[b] COc1ccccc1NC(=O)c1cnc(SCC(=O)NCC2CCCO2)n(C)c1=O
Answer: a. O=C(OCc1ccc([N+](=O)[O-])cc1)c1cc2ccccc2oc1=O
