Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 9.000\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. COc1ccc(OC)c(C(=O)NC(CC(N)=O)c2ccc(NCCN3CCOCC3)c([N+](=O)[O-])c2)c1
b. CCN(c1ccccc1)S(=O)(=O)c1ccc(OC)c(NC(=O)C2CC(=O)N(Cc3ccccc3)C2)c1
c. CCN1C(=S)N[C@@H](c2cccc(F)c2)C(C(=O)OC)=C1C
Answer: c. CCN1C(=S)N[C@@H](c2cccc(F)c2)C(C(=O)OC)=C1C
