Problem statement: Answer the multiple-choice question.
Query: Which drug has a 13.565\% human ether-à-go-go related gene (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(CN1C(=O)S/C(=C\c2ccc(O)c([N+](=O)[O-])c2)C1=O)Nc1ccc(N2CCOCC2)cc1
[b] O=C(O)CC/C(=N\NC(=O)CNC(=O)c1cccc(Cl)c1)c1ccccc1
Answer: a. O=C(CN1C(=O)S/C(=C\c2ccc(O)c([N+](=O)[O-])c2)C1=O)Nc1ccc(N2CCOCC2)cc1
