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: COc1ccc2c(O[C@@H]3C[C@H]4C(=O)N[C@]5(C(=O)NS(=O)(=O)C6CC6)C[C@H]5/C=C\CCCCN(C)C(=O)[C@@H]4C3)cc(-c3nc(C(C)C)cs3)nc2c1Cl
b: CCC(C)C(N)C(=O)OC[C@@H]1O[C@H](n2cc(F)c(=O)[nH]c2=O)C[C@H]1O
c: Cc1csc(NC(=O)C(C(=O)OC(C)C)=C2SCS2)n1
d: CC(C)(NC(=O)c1cc2ccccc2s1)C(=O)N[C@H](Cc1ccccc1)C(=O)NCCCN1CCOCC1
e: CC(=O)C(NC(=O)CN)c1ccc(O)cc1
