Which of the following is more basic than aniline?

In aniline, diphenylamine, and triphenylamine, the lone pair of electrons on the nitrogen atom is delocalized into the benzene ring(s) via resonance, drastically reducing its availability for protonation. In benzylamine (${\text{C}}_6{\text{H}}_5{\text{CH}}_2{\text{NH}}_2$), the $-{\text{NH}}_2$ group is separated from the ring by an $s{p}^3$ hybridized methylene group, preventing resonance, thereby making the lone pair fully available and benzylamine more basic.
