Task: Please answer the multiple choice question.
Question: Which molecule has the highest Caco-2 cell effective permeability?
Constraint: Even if you are uncertain, you must pick either a, b, c, d, or e without using any additional words.
Options:
a: Nc1c(CC(=O)[O-])cccc1C(=O)c1ccccc1.O.[Na+]
b: O=c1[nH]c(=O)n([C@@H]2O[C@H](CO)[C@@H](O)[C@@H]2O)cc1/C=C/Br
c: COC(=O)c1c(Cl)cccc1-c1ccc([C@@H](C)NC(=O)C2(NC(=O)C(F)(F)F)CC2)c(F)c1
d: O=C(O)c1cc(/N=N/c2ccc(S(=O)(=O)Nc3ccccn3)cc2)ccc1O
e: O=C(Nc1cccc(C(F)(F)F)c1)c1nscc1NCc1ccncc1
