Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.596\% 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 O.OC[C@H]1O[C@@H](n2cnc3c(NC4CCCC4)nc(Cl)nc32)[C@H](O)[C@@H]1O
b O=C(Nc1ccc(F)cc1)c1ccc(Br)c(S(=O)(=O)N2CCOCC2)c1
c COc1nc(N(C)C)nc(-n2nnc(C(C)=O)c2C)n1
Answer: c. COc1nc(N(C)C)nc(-n2nnc(C(C)=O)c2C)n1
