Task: Please answer the multiple choice question.
Question: Which molecule has the longest half life in humans after IV administration?
Constraint: Even if you are not sure, you must pick either a, b, c, or d 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) CC(C(=O)O)c1cccc(C(=O)c2ccccc2)c1
(c) C[C@H]1O[C@@H](n2cc(F)c(=O)[nH]c2=O)[C@H](O)[C@@H]1O
(d) CC1=C(C(=O)O)N2C(=O)[C@@H](NC(=O)[C@H](N)c3ccc(O)cc3)[C@H]2SC1
Answer: d
