Task: Answer the multiple choice question.
Question: Which compound has a 12.898\% 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: Cc1ccc2c(=O)cc(C(=O)Nc3ccc(S(=O)(=O)Nc4onc(C)c4C)cc3)oc2c1
b: O=S(=O)(Nc1cccc(Oc2ccc(Cl)cc2)n1)c1ccc(F)cc1
c: O=C(Nc1cccc(Cl)c1)c1cnn2cccnc12
Answer: c. O=C(Nc1cccc(Cl)c1)c1cnn2cccnc12
