Question: Which molecule has the longest half life time in humans after IV administration?
Constraint: Even if you are uncertain, you must pick either a, b, c, d, or e without using any other words.
Options:
a CC(C)n1c(/C=C/C(O)CC(O)CC(=O)O)c(-c2ccc(F)cc2)c2ccccc21
b NS(=O)(=O)c1cc(C(=O)O)c(NCc2ccco2)cc1Cl
c CC(C)C[C@H](NC(=O)[C@H](Cc1ccccc1)NC(=O)c1cnccn1)B(O)O
d CC(C)c1nc(N(C)S(C)(=O)=O)nc(-c2ccc(F)cc2)c1/C=C/[C@@H](O)C[C@@H](O)CC(=O)O
e CCCc1cc(=O)[nH]c(=S)[nH]1
