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 other words.
Options:
a: CNC1=Nc2ccc(Cl)cc2C(c2ccccc2)=[N+]([O-])C1
b: C[C@@H]1CC(=O)NN=C1c1ccc(NN=C(C#N)C#N)cc1
c: CCN1CCC[C@H]1CNC(=O)c1c(OC)ccc(Br)c1OC
d: CO/N=C(\C(=O)N[C@@H]1C(=O)N2C(C(=O)O)=C(C)CS[C@H]12)c1csc(N)n1
e: CCOC(=O)Nc1ccc(NCc2ccc(F)cc2)nc1N
Answer: b
