Task: Please answer the multiple choice question.
Question: Which molecule has the highest Caco-2 permeability?
Constraint: Even if you are uncertain, you must pick either a, b, c, or d without using any other words.
Options:
[a] Cc1cn([C@H]2C[C@H](N=[N+]=[N-])[C@@H](CO)O2)c(=O)[nH]c1=O
[b] NC(N)=N/N=C/c1c(Cl)cccc1Cl
[c] C[C@@](N)(Cc1ccc(O)c(O)c1)C(=O)O
[d] N=C(N)c1cccc(CC(CC(=O)N2CCNCC2)NS(=O)(=O)c2ccc3ccccc3c2)c1
Answer: c
