Task: Answer the multiple choice question.
Query: Which compound has a -3.679% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] C=CCN1C(=O)C(O)(CC(=O)c2ccc(OC)cc2OC)c2cc(Br)ccc21
[b] CCN(CC)S(=O)(=O)c1ccc(NC(=O)c2ccc(Sc3nncn3C)c([N+](=O)[O-])c2)cc1
Answer: a. C=CCN1C(=O)C(O)(CC(=O)c2ccc(OC)cc2OC)c2cc(Br)ccc21
