Task: Answer the multiple choice question.
Query: Which compound has a 17.856\% 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: COc1ccccc1N(CC(=O)N/N=C/c1ccc(C(=O)O)cc1)S(=O)(=O)c1ccc(C)cc1
b: Nc1nc(Nc2cccc(F)c2)nc(NCc2ccco2)c1[N+](=O)[O-]
c: Cc1ccc(NC(=S)N(Cc2ccco2)C(C)c2cccs2)c(Cl)c1
Answer: a. COc1ccccc1N(CC(=O)N/N=C/c1ccc(C(=O)O)cc1)S(=O)(=O)c1ccc(C)cc1
