Task: Please answer the multiple choice question.
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] NCC[C@H](O)C(=O)N[C@@H]1C[C@H](N)[C@@H](O[C@H]2O[C@H](CN)[C@@H](O)[C@H](O)[C@H]2O)[C@H](O)[C@H]1O[C@H]1O[C@H](CO)[C@@H](O)[C@H](N)[C@H]1O
[b] Nc1cc(-c2ccncc2)c[nH]c1=O
[c] CCOC(=O)C1=C(COCCN)NC(C)=C(C(=O)OC)C1c1ccccc1Cl
[d] COC(=O)C1=C(C)NC(C)=C(C(=O)OCC(C)C)C1c1ccccc1[N+](=O)[O-]
[e] O=C1c2cccc3c2[C@H](CCC3)CN1[C@@H]1CN2CCC1CC2
Answer: c
