Task: Answer the multiple choice question.
Query: Which compound exhibits a -9.656% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(NNC(=O)c1sccc1-n1cccc1)c1ccc(Cl)cc1
b: O=C(CN1C(=O)c2cccc3cccc1c23)N1CCN(c2cccc(Cl)c2)CC1
c: CCNC(=S)Nc1ccc(Cc2nc3ccccc3[nH]2)cc1
Answer: b. O=C(CN1C(=O)c2cccc3cccc1c23)N1CCN(c2cccc(Cl)c2)CC1
