Task: Please answer the multiple choice question.
Question: Which molecule has the highest Caco-2 cell permeability?
Constraint: Even if you are uncertain, you must pick either a, b, c, d, or e without using any other words.
Options:
a.) CC(=O)N[C@@H](Cc1ccccc1)C(N)=O
b.) CNC[C@H](O)c1ccc(O)c(O)c1
c.) O=c1[nH]c(=O)n([C@H]2O[C@@H](CO)[C@H](O)[C@H]2O)cc1/C=C/Br
d.) CC(C)(NC(=O)c1cc2ccccc2s1)C(=O)N[C@H](Cc1ccccc1)C(=O)NCCCN1CCOCC1
e.) NC(N)=N/N=C/c1c(Cl)cccc1Cl
Answer: e
