Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 6.054\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(NNC(=O)C1CC1)c1cccc([N+](=O)[O-])c1
b: CN(C)CCCN(C(=O)c1ccc(S(=O)(=O)N(C)C)cc1)c1nc2cc3c(cc2s1)OCO3.Cl
Answer: a. O=C(NNC(=O)C1CC1)c1cccc([N+](=O)[O-])c1
