Task: Please answer the multiple choice question.
Question: Which molecule has the longest drug 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 additional words.
Options:
a: CCN(CC)C(=O)/C(C#N)=C/c1cc(O)c(O)c([N+](=O)[O-])c1
b: CN(C)[C@@H]1C(O)=C(C(N)=O)C(=O)[C@@]2(O)C(O)=C3C(=O)c4c(O)cccc4[C@@](C)(O)[C@H]3C[C@@H]12
c: CN(C)[C@@H]1C(O)=C(C(N)=O)C(=O)[C@@]2(O)C(O)=C3C(=O)c4c(O)ccc(Cl)c4[C@@H](O)[C@H]3C[C@@H]12
d: CCCN(CCC)S(=O)(=O)c1ccc(C(=O)O)cc1
e: CN1C(C(=O)Nc2ccccn2)=C(O)c2sccc2S1(=O)=O
