Task: Answer the multiple choice question.
Question: Which drug exhibits a -14.284% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C1OC(c2cccc([N+](=O)[O-])c2)C2(CCCC2)C(=O)C12CCCCC2
b. CCOc1ccc(Cc2nnc(SCC(=O)Nc3ccccc3)n(N)c2=O)cc1
Answer: a. O=C1OC(c2cccc([N+](=O)[O-])c2)C2(CCCC2)C(=O)C12CCCCC2
