The correct option is D Benzylamine
Benzyl amine, C6H5CH2¨NH2 is more basic that aniline because be group C6H5CH2 electron donating group due to +I effect. So, It is able to Increase the electron of N of −NH2 group. Thus, due to higher electron density, rate of donation of free pair of electron is increased i.e., basic character is higher. Phenyl and nitro groups are electron attractive group. So, they are able to decrease the electron density of N of ¨NH2 group. Hence, they are less basic with aniline.
