Task: Please answer the multiple choice question.
Question: Which molecule has the highest Caco-2 cell permeability?
Constraint: Even if you are not sure, you must pick either a, b, c, d, or e without using any additional words.
Options:
(a) Cc1cn([C@H]2C[C@H](N=[N+]=[N-])[C@@H](CO)O2)c(=O)[nH]c1=O
(b) CC(=O)N[C@@H](Cc1ccccc1)C(N)=O
(c) COC(=O)c1cc(O)c(O)c(O)c1
(d) O=C(O)c1cc(Cl)ccc1O
(e) Cc1cn([C@H]2C[C@H](N=[N+]=[N-])[C@@H](CO)O2)c(=O)[nH]c1=O
Answer: e
