Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.856\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) CN1C(=O)NC(c2ccccc2[N+](=O)[O-])C2=C1CCCC2=O
(b) Cc1nc2ccc(NC(=O)c3cccc(S(=O)(=O)N(C)c4ccccc4)c3)cc2s1
(c) COC(=O)CCC(NS(=O)(=O)OCC(Cl)(Cl)Cl)c1ccccc1
Answer: a. CN1C(=O)NC(c2ccccc2[N+](=O)[O-])C2=C1CCCC2=O
