In which of the following reactions does the amine behaves as an acid ?

Amines are basic compounds They act as Lewis base due to the presence of lone pair electrons at nitrogen Amines also behave as base as well as Bronsted inductive effect, steric hindrance and resosnance. CH_(3)-NH_(2)+HOH hArr CH_(3)-NH_(3)^(+)+OH^(-) CH_(3)-NH_(2)+H^(+)Cl^(-)hArr CH_(3)-NH_(3)^(+)+Cl^(-) Alkyl groups and electron groups hence these groups increases the electron density at nitrogen as well as the basic amines character of amines. Basic character of teritary amines is reduced due to the steric hindrance of three alkyl groups. Experimentally it is observed that stronger bases have smaller values of pK_(b) greater value of K_(b) . Which among the following is the most basic in aqueous medium?
