Task: Please answer the multiple choice question.
Question: Which molecule has the highest Caco-2 permeability?
Constraint: Even if you are not sure, you must pick either a, b, or c without using any other words.
Options:
a. CC(C)[C@H](N)C(=O)OC[C@@H]1O[C@H](n2cc(F)c(=O)[nH]c2=O)C[C@H]1O
b. NC(=O)Cc1cc(/N=N/c2ccc(S(=O)(=O)Nc3ccccn3)cc2)ccc1O
c. CC[C@H](C)[C@H](N)C(=O)O[C@@H]1C[C@@H](n2cc(F)c(=O)[nH]c2=O)O[C@H]1CO
