Task: Answer the multiple-choice question.
Query: Which compound has a -51.429% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(Nc1cccc(S(=O)(=O)N2CCCCC2)c1)c1ccc([N+](=O)[O-])o1
b: S=c1nc(-c2ccccc2)n(CCN2CCOCC2)c2c1CCCC2
Answer: a. O=C(Nc1cccc(S(=O)(=O)N2CCCCC2)c1)c1ccc([N+](=O)[O-])o1
