Solution

The correct option is A True
Higher the value of $p K_{b}$ lesser is the acidic character.
Aniline has higher $p K_{b}$ than methylamine because methylamine is more acidic than aniline as in methylamine delocalization of lone pair of electrons belonging to nitrogen occurs as a result resonance structures are formed which increase the acidic character of methylamine, as a result, it has lesser $p K_{b}$ value.
