Task: Answer the multiple-choice question.
Question: Which compound has a 1.248\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(=O)c1cccc(Nc2nc(-c3cccc([N+](=O)[O-])c3)cs2)c1.Cl
b: Cc1ccc(-c2cc(-c3ccccc3)cc(-c3ccccc3)[n+]2-c2ccccc2)cc1.[O-][Cl+3]([O-])([O-])[O-]
c: O=C(CSc1nncn1-c1ccccc1)Nc1ccccc1
d: Cc1ccc(NC(=O)O/N=C/c2cccc([N+](=O)[O-])c2)cc1
Answer: a. CC(=O)c1cccc(Nc2nc(-c3cccc([N+](=O)[O-])c3)cs2)c1.Cl
